2 Mechanisms

2.1 PKCS #11 Mechanisms

A mechanism specifies precisely how a certain cryptographic process is to be performed. PKCS #11 implementations MAY use one or more mechanisms defined in this document.

The following table shows which Cryptoki mechanisms are supported by different cryptographic operations. For any particular token, of course, a particular operation MAY support only a subset of the mechanisms listed. There is also no guarantee that a token which supports one mechanism for some operation supports any other mechanism for any other operation (or even supports that same mechanism for any other operation). For example, even if a token is able to create RSA digital signatures with the CKM_RSA_PKCS mechanism, it may or may not be the case that the same token MAY also perform RSA encryption with CKM_RSA_PKCS.

¹ SR = SignRecover, VR = VerifyRecover.

² Single-part operations only.

³ Mechanism MUST only be used for wrapping, not unwrapping.

The remainder of this section presents in detail the mechanisms supported by Cryptoki and the parameters which are supplied to them.

In general, if a mechanism makes no mention of the ulMinKeyLen and ulMaxKeyLen fields of the CK_MECHANISM_INFO structure, then those fields have no meaning for that particular mechanism.

2.2 FORTEZZA timestamp

The FORTEZZA timestamp mechanism, denoted CKM_FORTEZZA_TIMESTAMP, is a mechanism for single-part signatures and verification. The signatures it produces and verifies are DSA digital signatures over the provided hash value and the current time.

It has no parameters.

Constraints on key types and the length of data are summarized in the following table. The input and output data MAY begin at the same location in memory.

Table 2, FORTEZZA Timestamp: Key and Data Length

Function	Key type	Input Length	Output Length
C_Sign¹	DSA private key	20	40
C_Verify¹	DSA public key	20,40²	N/A

^{1 Single-part operations only}

^{2 Data length,
signature length}

For this mechanism, the ulMinKeySIze and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of DSA prime sizes, in bits.

2.3 KEA

2.3.1 Definitions

This section defines the key type “CKK_KEA” for type CK_KEY_TYPE as used in the CKA_KEY_TYPE attribute of key objects.

Mechanisms:

CKM_KEA_KEY_PAIR_GEN

CKM_KEA_KEY_DERIVE

2.3.2 KEA mechanism parameters

2.3.2.1 CK_KEA_DERIVE_PARAMS; CK_KEA_DERIVE_PARAMS_PTR

CK_KEA_DERIVE_PARAMS is a structure that provides the parameters to the CKM_KEA_DERIVE mechanism. It is defined as follows:

typedef struct CK_KEA_DERIVE_PARAMS {

CK_BBOOL isSender;

CK_ULONG ulRandomLen;

CK_BYTE_PTR pRandomA;

CK_BYTE_PTR pRandomB;

CK_ULONG ulPublicDataLen;

CK_BYTE_PTR pPublicData;

} CK_KEA_DERIVE_PARAMS;

The fields of the structure have the following meanings:

isSender Option for generating the key (called a TEK). The value is CK_TRUE if the sender (originator) generates the TEK, CK_FALSE if the recipient is regenerating the TEK

ulRandomLen the size of random Ra and Rb in bytes

pRandomA pointer to Ra data

pRandomB pointer to Rb data

ulPublicDataLen other party’s KEA public key size

pPublicData pointer to other party’s KEA public key value

CK_KEA_DERIVE_PARAMS_PTR is a pointer to a CK_KEA_DERIVE_PARAMS.

2.3.3 KEA public key objects

KEA public key objects (object class CKO_PUBLIC_KEY, key type CKK_KEA) hold KEA public keys. The following table defines the KEA public key object attributes, in addition to the common attributes defined for this object class:

Table 3, KEA Public Key Object Attributes

Attribute	Data type	Meaning
CKA_PRIME^1,3	Big integer	Prime p (512 to 1024 bits, in steps of 64 bits)
CKA_SUBPRIME^1,3	Big integer	Subprime q (160 bits)
CKA_BASE^1,3	Big integer	Base g (512 to 1024 bits, in steps of 64 bits)
CKA_VALUE^1,4	Big integer	Public value y

^-Refer to [PKCS #11-Base] table 15 for footnotes

The CKA_PRIME, CKA_SUBPRIME and CKA_BASE attribute values are collectively the “KEA domain parameters”.

The following is a sample template for creating a KEA public key object:

CK_OBJECT_CLASS class = CKO_PUBLIC_KEY;

CK_KEY_TYPE keyType = CKK_KEA;

CK_UTF8CHAR label[] = “A KEA public key object”;

CK_BYTE prime[] = {…};

CK_BYTE subprime[] = {…};

CK_BYTE base[] = {…};

CK_BYTE value[] = {…};

CK_ATTRIBUTE template[] = {

{CKA_CLASS, &class, sizeof(class)},

{CKA_KEY_TYPE, &keyType, sizeof(keyType)},

{CKA_TOKEN, &true, sizeof(true)},

{CKA_LABEL, label, sizeof(label)-1},

{CKA_PRIME, prime, sizeof(prime)},

{CKA_SUBPRIME, subprime, sizeof(subprime)},

{CKA_BASE, base, sizeof(base)},

{CKA_VALUE, value, sizeof(value)}

};

2.3.4 KEA private key objects

KEA private key objects (object class CKO_PRIVATE_KEY, key type CKK_KEA) hold KEA private keys. The following table defines the KEA private key object attributes, in addition to the common attributes defined for this object class:

Table 4, KEA Private Key Object Attributes

Attribute	Data type	Meaning
CKA_PRIME^1,4,6	Big integer	Prime p (512 to 1024 bits, in steps of 64 bits)
CKA_SUBPRIME^1,4,6	Big integer	Subprime q (160 bits)
CKA_BASE^1,4,6	Big integer	Base g (512 to 1024 bits, in steps of 64 bits)
CKA_VALUE^1,4,6,7	Big integer	Private value x

Refer to [PKCS #11-Base] table 15 for footnotes

The CKA_PRIME, CKA_SUBPRIME and CKA_BASE attribute values are collectively the “KEA domain parameters”.

Note that when generating a KEA private key, the KEA parameters are not specified in the key’s template. This is because KEA private keys are only generated as part of a KEA key pair, and the KEA parameters for the pair are specified in the template for the KEA public key.

The following is a sample template for creating a KEA private key object:

CK_OBJECT_CLASS class = CKO_PRIVATE_KEY;

CK_KEY_TYPE keyType = CKK_KEA;

CK_UTF8CHAR label[] = “A KEA private key object”;

CK_BYTE subject[] = {…};

CK_BYTE id[] = {123};

CK_BYTE prime[] = {…};

CK_BYTE subprime[] = {…};

CK_BYTE base[] = {…};

CK_BYTE value[] = {…];

CK_BBOOL true = CK_TRUE;

CK_ATTRIBUTE template[] = {

{CKA_CLASS, &class, sizeof(class)},

{CKA_KEY_TYPE, &keyType, sizeof(keyType)},Algorithm, as defined by NISTS

{CKA_TOKEN, &true, sizeof(true)},

{CKA_LABEL, label, sizeof(label) -1},

{CKA_SUBJECT, subject, sizeof(subject)},

{CKA_ID, id, sizeof(id)},

{CKA_SENSITIVE, &true, sizeof(true)},

{CKA_DERIVE, &true, sizeof(true)},

{CKA_PRIME, prime, sizeof(prime)},

{CKA_SUBPRIME, subprime, sizeof(subprime)},

{CKA_BASE, base, sizeof(base)],

{CKA_VALUE, value, sizeof(value)}

};

2.3.5 KEA key pair generation

The KEA key pair generation mechanism, denoted CKM_KEA_KEY_PAIR_GEN, generates key pairs for the Key Exchange Algorithm, as defined by NIST’s “SKIPJACK and KEA Algorithm Specification Version 2.0”, 29 May 1998.

It does not have a parameter.

The mechanism generates KEA public/private key pairs with a particular prime, subprime and base, as specified in the CKA_PRIME, CKA_SUBPRIME, and CKA_BASE attributes of the template for the public key. Note that this version of Cryptoki does not include a mechanism for generating these KEA domain parameters.

The mechanism contributes the CKA_CLASS, CKA_KEY_TYPE and CKA_VALUE attributes to the new public key and the CKA_CLASS, CKA_KEY_TYPE, CKA_PRIME, CKA_SUBPRIME, CKA_BASE, and CKA_VALUE attributes to the new private key. Other attributes supported by the KEA public and private key types (specifically, the flags indicating which functions the keys support) MAY also be specified in the templates for the keys, or else are assigned default initial values.

For this mechanism, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of KEA prime sizes, in bits.

2.3.6 KEA key derivation

The KEA key derivation mechanism, denoted CKM_DEA_DERIVE, is a mechanism for key derivation based on KEA, the Key Exchange Algorithm, as defined by NIST’s “SKIPJACK and KEA Algorithm Specification Version 2.0”, 29 May 1998.

It has a parameter, a CK_KEA_DERIVE_PARAMS structure.

This mechanism derives a secret value, and truncates the result according to the CKA_KEY_TYPE attribute of the template and, if it has one and the key type supports it, the CKA_VALUE_LEN attribute of the template. (The truncation removes bytes from the leading end of the secret value.) The mechanism contributes the result as the CKA_VALUE attribute of the new key; other attributes required by the key type must be specified in the template.

As defined in the Specification, KEA MAY be used in two different operational modes: full mode and e-mail mode. Full mode is a two-phase key derivation sequence that requires real-time parameter exchange between two parties. E-mail mode is a one-phase key derivation sequence that does not require real-time parameter exchange. By convention, e-mail mode is designated by use of a fixed value of one (1) for the KEA parameter R_b (pRandomB).

The operation of this mechanism depends on two of the values in the supplied CK_KEA_DERIVE_PARAMS structure, as detailed in the table below. Note that in all cases, the data buffers pointed to by the parameter structure fields pRandomA and pRandomB must be allocated by the caller prior to invoking C_DeriveKey. Also, the values pointed to by pRandomA and pRandomB are represented as Cryptoki “Big integer” data (i.e., a sequence of bytes, most significant byte first).

Table 5, KEA Parameter Values and Operations

Value of boolean isSender	Value of big integer pRandomB	Token Action (after checking parameter and template values)
CK_TRUE	0	Compute KEA R_avalue, store it in pRandomA, return CKR_OK. No derived key object is created.
CK_TRUE	1	Compute KEA R_a value, store it in pRandomA, derive key value using e-mail mode, create key object, return CKR_OK.
CK_TRUE	>1	Compute KEA R_a value, store it in pRandomA, derive key value using full mode, create key object, return CKR_OK
CK_FALSE	0	Compute KEA R_b value, store it in pRandomB, return CKR_OK. No derived key object is created.
CK_FALSE	1	Derive key value using e-mail mode, create key object, return CKR_OK.
CK_FALSE	>1	Derive key value using full mode, create key object, return CKR_OK.

Note that the parameter value pRandomB == 0 is a flag that the KEA mechanism is being invoked to compute the party’s public random value (R_a or R_b, for sender or recipient, respectively), not to derive a key. In these cases, any object template supplied as the C_DeriveKey pTemplate argument should be ignored.

This mechanism has the following rules about key sensitivity and extractability[*]:

The CKA_SENSITIVE and CKA_EXTRACTABLE attributes in the template for the new key MAY both be specified to be either CK_TRUE or CK_FALSE. If omitted, these attributes each take on some default value.
If the base key has its CKA_ALWAYS_SENSITIVE attribute set to CK_FALSE, then the derived key MUST as well. If the base key has its CKA_ALWAYS_SENSITIVE attribute set to CK_TRUE, then the derived has its CKA_ALWAYS_SENSITIVE attribute set to the same value as its CKA_SENSITIVE attribute.
Similarly, if the base key has its CKA_NEVER_EXTRACTABLE attribute set to CK_FALSE, then the derived key MUST, too. If the base key has its CKA_NEVER_EXTRACTABLE attribute set to CK_TRUE, then the derived key has its CKA_NEVER_EXTRACTABLE attribute set to the opposite value from its CKA_EXTRACTABLE attribute.

For this mechanism, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of KEA prime sizes, in bits.

2.4 RC2

2.4.1 Definitions

RC2 is a block cipher which is trademarked by RSA Security. It has a variable keysizse and an additional parameter, the “effective number of bits in the RC2 search space”, which MAY take on values in the range 1-1024, inclusive. The effective number of bits in the RC2 search space is sometimes specified by an RC2 “version number”; this “version number” is not the same thing as the “effective number of bits”, however. There is a canonical way to convert from one to the other.

This section defines the key type “CKK_RC2” for type CK_KEY_TYPE as used in the CKA_KEY_TYPE attribute of key objects.

Mechanisms:

CKM_RC2_KEY_GEN

CKM_RC2_ECB

CKM_RC2_CBC

CKM_RC2_MAC

CKM_RC2_MAC_GENERAL

CKM_RC2_CBC_PAD

2.4.2 RC2 secret key objects

RC2 secret key objects (object class CKO_SECRET_KEY, key type CKK_RC2) hold RC2 keys. The following table defines the RC2 secret key object attributes, in addition to the common attributes defined for this object class:

Table 6, RC2 Secret Key Object Attributes

{CKA_VALUE, value, sizeof(value)}

};

2.4.3 RC2 mechanism parameters

2.4.3.1 CK_RC2_PARAMS; CK_RC2_PARAMS_PTR

CK_RC2_PARAMS provides the parameters to the CKM_RC2_ECB and CMK_RC2_MAC mechanisms. It holds the effective number of bits in the RC2 search space. It is defined as follows:

typedef CK_ULONG CK_RC2_PARAMS;

typedef struct CK_RC2_CBC_PARAMS {

CK_ULONG ulEffectiveBits;

CK_BYTE iv[8];

} CK_RC2_CBC_PARAMS;

2.4.4 RC2 key generation

The RC2 key generation mechanism, denoted CKM_RC2_KEY_GEN, is a key generation mechanism for RSA Security’s block cipher RC2.

It does not have a parameter.

The mechanism generates RC2 keys with a particular length in bytes, as specified in the CKA_VALUE_LEN attribute of the template for the key.

The mechanism contributes the CKA_CLASS, CKA_KEY_TYPE, and CKA_VALUE attributes to the new key. Other attributes supported by the RC2 key type (specifically, the flags indicating which functions the key supports) MAY be specified in the template for the key, or else are assigned default initial values.

For this mechanism, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of RC2 key sizes, in bits.

2.4.5 RC2-ECB

RC2-ECB, denoted CKM_RC2_ECB, is a mechanism for single- and multiple-part encryption and decryption; key wrapping; and key unwrapping, based on RSA Security’s block cipher RC2 and electronic codebook mode as defined in FIPS PUB 81.

It has a parameter, a CK_RC2_PARAMS, which indicates the effective number of bits in the RC2 search space.

This mechanism MAY wrap and unwrap any secret key. Of course, a particular token MAY not be able to wrap/unwrap every secret key that it supports. For wrapping, the mechanism encrypts the value of the CKA_VALUE attribute of the key that is wrapped, padded on the trailing end with up to seven null bytes so that the resulting length is a multiple of eight. The output data is the same length as the padded input data. It does not wrap the key type, key length, or any other information about the key; the application must convey these separately.

For unwrapping, the mechanism decrypts the wrapped key, and truncates the result according to the CKA_KEY_TYPE attribute of the template and, if it has one, and the key type supports it, the CKA_VALUE_LEN attribute of the template. The mechanism contributes the result as the CKA_VALUE attribute of the new key; other attributes required by the key type must be specified in the template.

Constraints on key types and the length of data are summarized in the following table:

Table 7 RC2-ECB: Key and Data Length

Function	Key type	Input length	Output length	Comments
C_Encrypt	RC2	Multiple of 8	Same as input length	No final part
C_Decrypt	RC2	Multiple of 8	Same as input length	No final part
C_WrapKey	RC2	Any	Input length rounded up to multiple of 8
C_UnwrapKey	RC2	Multiple of 8	Determined by type of key being unwrapped or CKA_VALUE_LEN

For this mechanism, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of RC2 effective number of bits.

2.4.6 RC2-CBC

RC2_CBC, denoted CKM_RC2_CBC, is a mechanism for single- and multiple-part encryption and decryption; key wrapping; and key unwrapping, based on RSA Security’s block cipher RC2 and cipher-block chaining mode as defined in FIPS PUB 81.

It has a parameter, a CK_RC2_CBC_PARAMS structure, where the first field indicates the effective number of bits in the RC2 search space, and the next field is the initialization vector for cipher block chaining mode.

Constraints on key types and the length of data are summarized in the following table:

Table 8, RC2-CBC: Key and Data Length

Function	Key type	Input length	Output length	Comments
C_Encrypt	RC2	Multiple of 8	Same as input length	No final part
C_Decrypt	RC2	Multiple of 8	Same as input length	No final part
C_WrapKey	RC2	Any	Input length rounded up to multiple of 8
C_UnwrapKey	RC2	Multiple of 8	Determined by type of key being unwrapped or CKA_VALUE_LEN

For this mechanism, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of RC2 effective number of bits.

2.4.7 RC2-CBC with PKCS padding

RC2-CBC with PKCS padding, denoted CKM_RC2_CBC_PAD, is a mechanism for single- and multiple-part encryption and decryption; key wrapping; and key unwrapping, based on RSA Security’s block cipher RC2; cipher-block chaining mode as defined in FIPS PUB 81; and the block cipher padding method detailed in PKCS #7.

It has a parameter, a CK_RC2_CBC_PARAMS structure, where the first field indicates the effective number of bits in the RC2 search space, and the next field is the initialization vector.

The PKCS padding in this mechanism allows the length of the plaintext value to be recovered from the ciphertext value. Therefore, when unwrapping keys with this mechanism, no value should be specified for the CKA_VALUE_LEN attribute.

In addition to being able to wrap and unwrap secret keys, this mechanism MAY wrap and unwrap RSA, Diffie-Hellman, X9.42 Diffie-Hellman, EC (also related to ECDSA) and DSA private keys (see [PKCS #11-Curr], Miscellaneous simple key derivation mechanisms for details). The entries in the table below for data length constraints when wrapping and unwrapping keys do not apply to wrapping and unwrapping private keys.

Constraints on key types and the length of data are summarized in the following table:

Table 9, RC2-CBC with PKCS Padding: Key and Data Length

Function	Key type	Input length	Output length
C_Encrypt	RC2	Any	Input length rounded up to multiple of 8
C_Decrypt	RC2	Multiple of 8	Between 1 and 8 bytes shorter than input length
C_WrapKey	RC2	Any	Input length rounded up to multiple of 8

It has a parameter, a CK_RC2_MAC_GENERAL_PARAMS structure, which specifies the effective number of bits in the RC2 search space and the output length desired from the mechanism.

The output bytes from this mechanism are taken from the start of the final RC2 cipher block produced in the MACing process.

Constraints on key types and the length of data are summarized in the following table:

Table 10, General-length RC2-MAC: Key and Data Length

Function	Key type	Data length	Signature length
C_Sign	RC2	Any	0-8, as specified in parameters
C_Verify	RC2	Any	0-8, as specified in parameters

For this mechanism, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of RC2 effective number of bits.

2.4.9 RC2-MAC

RC2-MAC, denoted by CKM_RC2_MAC, is a special case of the general-length RC2-MA mechanism (see Section 2.4.8). Instead of taking a CK_RC2_MAC_GENERAL_PARAMS parameter, it takes a CK_RC2_PARAMS parameter, which only contains the effective number of bits in the RC2 search space. RC2-MAC produces and verifies 4-byte MACs.

Constraints on key types and the length of data are summarized in the following table:

Table 11, RC2-MAC: Key and Data Length

2.7.8 General block cipher mechanism parameters

2.7.8.1 CK_MAC_GENERAL_PARAMS; CK_MAC_GENERAL_PARAMS_PTR

CK_MAC_GENERAL_PARAMS provides the parameters to the general-length MACing mechanisms of the DES, DES3 (triple-DES), CAST, CAST3, CAST128 (CAST5), IDEA, CDMF and AES ciphers. It also provides the parameters to the general-length HMACing mechanisms (i.e., MD2, MD5, SHA-1, SHA-256, SHA-384, SHA-512, RIPEMD-128 and RIPEMD-160) and the two SSL 3.0 MACing mechanisms, (i.e., MD5 and SHA-1). It holds the length of the MAC that these mechanisms produce. It is defined as follows:

typedef CK_ULONG CK_MAC_GENERAL_PARAMS;

CK_MAC_GENERAL_PARAMS_PTR is a pointer to a CK_MAC_GENERAL_PARAMS.

2.7.9 General block cipher key generation

Cipher <NAME> has a key generation mechanism, “<NAME> key generation”, denoted by CKM_<NAME>_KEY_GEN.

This mechanism does not have a parameter.

The mechanism contributes the CKA_CLASS, CKA_KEY_TYPE, and CKA_VALUE attributes to the new key. Other attributes supported by the key type (specifically, the flags indicating which functions the key supports) MAY be specified in the template for the key, or else are assigned default initial values.

When DES keys or CDMF keys are generated, their parity bits are set properly, as specified in FIPS PUB 46-3. Similarly, when a triple-DES key is generated, each of the DES keys comprising it has its parity bits set properly.

When DES or CDMF keys are generated, it is token-dependent whether or not it is possible for “weak” or “semi-weak” keys to be generated. Similarly, when triple-DES keys are generated, it is token-dependent whether or not it is possible for any of the component DES keys to be “weak” or “semi-weak” keys.

When CAST, CAST3, or CAST128 (CAST5) keys are generated, the template for the secret key must specify a CKA_VALUE_LEN attribute.

For this mechanism, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure MAY be used. The CAST, CAST3, and CAST128 (CAST5) ciphers have variable key sizes, and so for the key generation mechanisms for these ciphers, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of key sizes, in bytes. For the DES, DES3 (triple-DES), IDEA and CDMF ciphers, these fields and not used.

2.7.10 General block cipher ECB

Cipher <NAME> has an electronic codebook mechanism, “<NAME>-ECB”, denoted CKM_<NAME>_ECB. It is a mechanism for single- and multiple-part encryption and decryption; key wrapping; and key unwrapping with <NAME>.

It does not have a parameter.

This mechanism MAY wrap and unwrap any secret key. Of course, a particular token MAY not be able to wrap/unwrap every secret key that it supports. For wrapping, the mechanism encrypts the value of the CKA_VALUE attribute of the key that is wrapped, padded on the trailing end with null bytes so that the resulting length is a multiple of <NAME>’s blocksize. The output data is the same length as the padded input data. It does not wrap the key type, key length or any other information about the key; the application must convey these separately.

Constraints on key types and the length of data are summarized in the following table:

Table 26, General Block Cipher ECB: Key and Data Length

Function	Key type	Input length	Output length	Comments
C_Encrypt	<NAME>	Multiple of blocksize	Same as input length	No final part
C_Decrypt	<NAME>	Multiple of blocksize	Same as input length	No final part
C_WrapKey	<NAME>	Any	Input length rounded up to multiple of blocksize
C_UnwrapKey	<NAME>	Any	Determined by type of key being unwrapped or CKA_VALUE_LEN

For this mechanism, the ulMinKeySize and ulMaxKeySIze fields of the CK_MECHANISM_INFO structure MAY be used. The CAST, CAST3, and CAST128 (CAST5) ciphers have variable key sizes, and so for these ciphers, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of key sizes, in bytes. For the DES, DES3 (triple-DES), IDEA and CDMF ciphers, these fields are not used.

2.7.11 General block cipher CBC

Cipher <NAME> has a cipher-block chaining mode, “<NAME>-CBC”, denoted CKM_<NAME>_CBC. It is a mechanism for single- and multiple-part encryption and decryption; key wrapping; and key unwrapping with <NAME>.

It has a parameter, an initialization vector for cipher block chaining mode. The initialization vector has the same length as <NAME>’s blocksize.

Constraints on key types and the length of data are summarized in the following table:

Table 27, General Block Cipher CBC; Key and Data Length

Function	Key type	Input length	Output length	Comments
C_Encrypt	<NAME>	Multiple of blocksize	Same as input length	No final part
C_Decrypt	<NAME>	Multiple of blocksize	Same as input length	No final part
C_WrapKey	<NAME>	Any	Input length rounded up to multiple of blocksize
C_UnwrapKey	<NAME>	Any	Determined by type of key being unwrapped or CKA_VALUE_LEN

For this mechanism, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure MAY be used. The CAST, CAST3, and CAST128 (CAST5) ciphers have variable key sizes, and so for these ciphers, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of key sizes, in bytes. For the DES, DES3 (triple-DES), IDEA, and CDMF ciphers, these fields are not used.

2.7.12 General block cipher CBC with PCKS padding

Cipher <NAME> has a cipher-block chaining mode with PKCS padding, “<NAME>-CBC with PKCS padding”, denoted CKM_<NAME>_CBC_PAD. It is a mechanism for single- and multiple-part encryption and decryption; key wrapping; and key unwrapping with <NAME>. All ciphertext is padded with PKCS padding.

It has a parameter, an initialization vector for cipher block chaining mode. The initialization vector has the same length as <NAME>’s blocksize.

In addition to being able to wrap and unwrap secret keys, this mechanism MAY wrap and unwrap RSA, Diffie-Hellman, X9.42 Diffie-Hellman, EC (also related to ECDSA) and DSA private keys. The entries in the table below for data length constraints when wrapping and unwrapping keys to not apply to wrapping and unwrapping private keys.

Constraints on key types and the length of data are summarized in the following table:

Table 28, General Block Cipher CBC with PKCS Padding: Key and Data Length

Function	Key type	Input length	Output length
C_Encrypt	<NAME>	Any	Input length rounded up to multiple of blocksize
C_Decrypt	<NAME>	Multiple of blocksize	Between 1 and blocksize bytes shorter than input length
C_WrapKey	<NAME>	Any	Input length rounded up to multiple of blocksize
C_UnwrapKey	<NAME>	Multiple of blocksize	Between 1 and blocksize bytes shorter than input length

For this mechanism, the ulMinKeySIze and ulMaxKeySize fields of the CK_MECHANISM_INFO structure MAY be used. The CAST, CAST3 and CAST128 (CAST5) ciphers have variable key sizes, and so for these ciphers, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of key sizes, in bytes. For the DES, DES3 (triple-DES), IDEA, and CDMF ciphers, these fields are not used.

2.7.13 General-length general block cipher MAC

Cipher <NAME> has a general-length MACing mode, “General-length <NAME>-MAC”, denoted CKM_<NAME>_MAC_GENERAL. It is a mechanism for single-and multiple-part signatures and verification, based on the <NAME> encryption algorithm and data authentication as defined in FIPS PUB 113.

It has a parameter, a CK_MAC_GENERAL_PARAMS, which specifies the size of the output.

The output bytes from this mechanism are taken from the start of the final cipher block produced in the MACing process.

Constraints on key types and the length of input and output data are summarized in the following table:

Table 29, General-length General Block Cipher MAC: Key and Data Length

Function	Key type	Data length	Signature length
C_Sign	<NAME>	Any	0-blocksize, depending on parameters
C_Verify	<NAME>	Any	0-blocksize, depending on parameters

For this mechanism, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure MAY be used. The CAST, CAST3, and CASt128 (CAST5) ciphers have variable key sizes, and so for these ciphers, the ulMinKeySize and ulMaxKeySize fields of the CK_MECHANISM_INFO structure specify the supported range of key sizes, in bytes. For the DES, DES3 (triple-DES), IDEA and CDMF ciphers, these fields are not used.

2.7.14 General block cipher MAC

Cipher <NAME> has a MACing mechanism, “<NAME>-MAC”, denoted CKM_<NAME>_MAC. This mechanism is a special case of the CKM_<NAME>_MAC_GENERAL mechanism described above. It produces an output of size half as large as <NAME>’s blocksize.

This mechanism has no parameters.

Constraints on key types and the length of data are summarized in the following table:

Table 30, General Block cipher MAC: Key and Data Length

Function	Key type	Data length	Signature length
C_Sign	<NAME>	Any	[blocksize/2]
C_Verify	<NAME>	Any	[blocksize/2]

It is not clear that any tokens exist (or will ever exist) which permit an application to create a BATON key with a specified value. Nonetheless, we provide templates for doing so.

The following is a sample template for creating a BATON MEK secret key object:

CK_OBJECT_CLASS class = CKO_SECRET_KEY;

CK_KEY_TYPE keyType = CKK_BATON;

CK_UTF8CHAR label[] = “A BATON MEK secret key object”;

CK_BYTE value[40] = {…};

CK_BBOOL true = CK_TRUE;

CK_ATTRIBUTE template[] = {

2.15 PKCS #12 password-based encryption/authentication mechanisms

2.15.1 Definitions

The mechanisms in this section are for generating keys and IVs for performing password-based encryption or authentication. The method used to generate keys and IVs is based on a method that was specified in PKCS #12.

We specify here a general method for producing various types of pseudo-random bits from a password, p; a string of salt bits, s; and an iteration count, c. The “type” of pseudo-random bits to be produced is identified by an identification byte, ID, described at the end of this section.

Let H be a hash function built around a compression function ∫:Z₂^u × Z₂^v → Z₂^u (that is, H has a chaining variable and output of length u bits, and the message input to the compression function of H is v bits). For MD2 and MD5, u=128 and v=512; for SHA-1, u=160 and v=512.

We assume here that u and v are both multiples of 8, as are the lengths in bits of the password and salt strings and the number n of pseudo-random bits required. In addition, u and v are of course nonzero.

1. Construct a string, D (the “diversifier”), by concatenating v/8 copies of ID.

Concatenate copies of the salt together to create a string S of length v⋅⎡s/v⎤ bits (the final copy of the salt MAY be truncated to create S). Note that if the salt is the empty string, then so is S
Concatenate copies of the password together to create a string P of length v⋅⎡p/v⎤ bits (the final copy of the password MAY be truncated to create P). Note that if the password is the empty string, then so is P.
Set I=S||P to be the concatenation of S and P.
Set j=⎡n/u⎤.
For i=1, 2, …, j, do the following:

Set Ai=Hc(D||I), the cth hash of D||I. That is, compute the hash of D||I; compute the hash of that hash; etc.; continue in this fashion until a total of c hashes have been computed, each on the result of the previous hash.
Concatenate copies of Ai to create a string B of length v bits (the final copy of Ai MAY be truncated to create B).
Treating I as a concatenation I0, I1, …, Ik-1 of v-bit blocks, where k=⎡s/v⎤+⎡p/v⎤, modify I by setting Ij=(Ij+B+1) mod 2v for each j. To perform this addition, treat each v-bit block as a binary number represented most-significant bit first

Concatenate A1, A2, …, Aj together to form a pseudo-random bit string, A.
Use the first n bits of A as the output of this entire process

When the password-based encryption mechanisms presented in this section are used to generate a key and IV (if needed) from a password, salt, and an iteration count, the above algorithm is used. To generate a key, the identifier byte ID is set to the value 1; to generate an IV, the identifier byte ID is set to the value 2.

When the password-based authentication mechanism presented in this section is used to generate a key from a password, salt and an iteration count, the above algorithm is used. The identifier ID is set to the value 3.

It has a parameter, a CK_PBE_PARAMS structure. The parameter specifies the input information for the key generation process. The parameter also has a field to hold the location of an application-supplied buffer which receives an IV; for this mechanism, the contents of this field are ignored, since RC4 does not require an IV.

The key produced by this mechanism will typically be used for performing password-based encryption.

SHA-1-PBE for 40-bit RC4, denoted CKM_PBE_SHA1_RC4_40, is a mechanism used for generating a 40-bit RC4 secret key from a password and a salt value by using the SHA-1 digest algorithm and an iteration count. The method used to generate the key is described above.

It has a parameter, a CK_PBE_PARAMS structure. The parameter specifies the input information for the key generation process and the location of an application-supplied buffer which receives the 8-byte IV generated by the mechanism.

When the key and IV generated by this mechanism are used to encrypt or decrypt, the effective number of bits in the RC2 search space should be set to 128. This ensures compatibility with the ASN.1 Object Identifier pbeWithSHA1And128BitRC2-CBC.

The key and IV produced by this mechanism will typically be used for performing password-based encryption.

The key and IV produced by this mechanism will typically be used for performing password-based encryption

Function	Data length	Digest length
C_Digest	Any	16

2.16.3 General-length RIPE-MD 128-HMAC

The general-length RIPE-MD 128-HMAC mechanism, denoted CKM_RIPEMD128_HMAC_GENERAL, is a mechanism for signatures and verification. It uses the HMAC construction, based on the RIPE-MD 128 hash function. The keys it uses are generic secret keys.

It has a parameter, a CK_MAC_GENERAL_PARAMS, which holds the length in bytes of the desired output. This length should be in the range 0-16 (the output size of RIPE-MD 128 is 16 bytes). Signatures (MACs) produced by this mechanism MUST be taken from the start of the full 16-byte HMAC output.

2.17 SET

2.17.1 Definitions

Mechanisms:

CKM_KEY_WRAP_SET_OAEP

2.17.2 SET mechanism parameters

2.17.2.1 CK_KEY_WRAP_SET_OAEP_PARAMS; CK_KEY_WRAP_SET_OAEP_PARAMS_PTR

CK_KEY_WRAP_SET_OAEP_PARAMS is a structure that provides the parameters to the CKM_KEY_WRAP_SET_OAEP mechanism. It is defined as follows:

typedef struct CK_KEY_WRAP_SET_OAEP_PARAMS {

CK_BYTE bBC;

CK_BYTE_PTR pX;

CK_ULONG ulXLen;

} CK_KEY_WRAP_SET_OAEP_PARAMS;

The fields of the structure have the following meanings:

bBC block contents byte

pX concatenation of hash of plaintext data (if present) and extra data (if present)

ulXLen length in bytes of concatenation of hash of plaintext data (if present) and extra data (if present). 0 if neither is present.

CK_KEY_WRAP_SET_OAEP_PARAMS_PTR is a pointer to a CK_KEY_WRAP_SET_OAEP_PARAMS.

2.17.3 OAEP key wrapping for SET

The OAEP key wrapping for SET mechanism, denoted CKM_KEY_WRAP_SET_OAEP, is a mechanism for wrapping and unwrapping a DES key with an RSA key. The hash of some plaintext data and/or some extra data MAY be wrapped together with the DES key. This mechanism is defined in the SET protocol specifications.

It takes a parameter, a CK_KEY_WRAP_SET_OAEP_PARAMS structure. This structure holds the “Block Contents” byte of the data and the concatenation of the hash of plaintext data (if present) and the extra data to be wrapped (if present). If neither the hash nor the extra data is present, this is indicated by the ulXLen field having the value 0.

When this mechanism is used to unwrap a key, the concatenation of the hash of plaintext data (if present) and the extra data (if present) is returned following the convention described [PKCS #11-Curr], Miscellaneous simple key derivation mechanisms. Note that if the inputs to C_UnwrapKey are such that the extra data is not returned (e.g. the buffer supplied in the CK_KEY_WRAP_SET_OAEP_PARAMS structure is NULL_PTR), then the unwrapped key object MUST NOT be created, either.

Be aware that when this mechanism is used to unwrap a key, the bBC and pX fields of the parameter supplied to the mechanism MAY be modified.

If an application uses C_UnwrapKey with CKM_KEY_WRAP_SET_OAEP, it may be preferable for it simply to allocate a 128-byte buffer for the concatenation of the hash of plaintext data and the extra data (this concatenation MUST NOT be larger than 128 bytes), rather than calling C_UnwrapKey twice. Each call of C_UnwrapKey with CKM_KEY_WRAP_SET_OAEP requires an RSA decryption operation to be performed, and this computational overhead MAY be avoided by this means.

2.18 LYNKS

2.18.1 Definitions

Mechanisms:

CKM_KEY_WRAP_LYNKS

2.18.2 LYNKS key wrapping

The LYNKS key wrapping mechanism, denoted CKM_KEY_WRAP_LYNKS, is a mechanism for wrapping and unwrapping secret keys with DES keys. It MAY wrap any 8-byte secret key, and it produces a 10-byte wrapped key, containing a cryptographic checksum.

It does not have a parameter.

To wrap an 8-byte secret key K with a DES key W, this mechanism performs the following steps:

Initialize two 16-bit integers, sum₁ and sum₂, to 0
Loop through the bytes of K from first to last.
Set sum₁= sum₁+the key byte (treat the key byte as a number in the range 0-255).
Set sum₂= sum₂+ sum₁.
Encrypt K with W in ECB mode, obtaining an encrypted key, E.
Concatenate the last 6 bytes of E with sum₂, representing sum₂ most-significant bit first. The result is an 8-byte block, T
Encrypt T with W in ECB mode, obtaining an encrypted checksum, C.
Concatenate E with the last 2 bytes of C to obtain the wrapped key.

When unwrapping a key with this mechanism, if the cryptographic checksum does not check out properly, an error is returned. In addition, if a DES key or CDMF key is unwrapped with this mechanism, the parity bits on the wrapped key must be set appropriately. If they are not set properly, an error is returned.

3 PKCS #11 Implementation Conformance

An implementation is a conforming implementation if it meets the conditions specified in one or more server profiles specified in [PKCS #11-Prof].

A PKCS #11 implementation SHALL be a conforming PKCS #11 implementation.

If a PKCS #11 implementation claims support for a particular profile, then the implementation SHALL conform to all normative statements within the clauses specified for that profile and for any subclauses to each of those clauses.
