Detailed Description
CK_X9_42_MQV_DERIVE_PARAMS, CK_X9_42_MQV_DERIVE_PARAMS_PTR
CK_X9_42_MQV_DERIVE_PARAMS is a structure that provides the parameters to the CKM_X9_42_MQV_DERIVE key derivation mechanism, where each party contributes two key pairs. The structure is defined as follows: | kdf | key derivation function used on the shared secret value |
| ulOtherInfoLen | the length in bytes of the other info |
| pOtherInfo | some data shared between the two parties |
| ulPublicDataLen | the length in bytes of the other party's first X9.42 Diffie-Hellman public key |
| pPublicData | pointer to other party's first X9.42 Diffie-Hellman public key value |
| ulPrivateDataLen | the length in bytes of the second X9.42 Diffie-Hellman private key |
| hPrivateData | key handle for second X9.42 Diffie-Hellman private key value |
| ulPublicDataLen2 | the length in bytes of the other party's second X9.42 Diffie-Hellman public key |
| pPublicData2 | pointer to other party's second X9.42 Diffie-Hellman public key value |
| publicKey | Handle to the first party's ephemeral public key |
With the key derivation function CKD_NULL, pOtherInfo must be NULL and ulOtherInfoLen must be zero. With the key derivation function CKD_SHA1_KDF_ASN1, pOtherInfo must be supplied, which contains an octet string, specified in ASN.1 DER encoding, consisting of mandatory and optional data shared by the two parties intending to share the shared secret. With the key derivation function CKD_SHA1_KDF_CONCATENATE, an optional pOtherInfo may be supplied, which consists of some data shared by the two parties intending to share the shared secret. Otherwise, pOtherInfo must be NULL and ulOtherInfoLen must be zero.
CK_X9_42_MQV_DERIVE_PARAMS_PTR is a pointer to a CK_X9_42_MQV_DERIVE_PARAMS.
