Detailed Description

CK_WTLS_KEY_MAT_PARAMS; CK_WTLS_KEY_MAT_PARAMS_PTR

CK_WTLS_KEY_MAT_PARAMS is a structure that provides the parameters to the CKM_WTLS_SEVER_KEY_AND_MAC_DERIVE and the CKM_WTLS_CLIENT_KEY_AND_MAC_DERIVE mechanisms. It is defined as follows:

DigestMechanism the mechanism type of the digest mechanism to be used (possible types can be found in [WTLS])
ulMacSizeInBits the length (in bits) of the MACing key agreed upon during the protocol handshake phase
ulKeySizeInBits the length (in bits) of the secret key agreed upon during the handshake phase
ulIVSizeInBits the length (in bits) of the IV agreed upon during the handshake phase. If no IV is required, the length should be set to 0.
ulSequenceNumber The current sequence number used for records sent by the client and server respectively
bIsExport a boolean value which indicates whether the keys have to be derived for an export version of the protocol. If this value is true (i.e. the keys are exportable) then ulKeySizeInBits is the length of the key in bits before expansion. The length of the key after expansion is determined by the information found in the template sent along with this mechanism during a C_DeriveKey function call (either the CKA_KEY_TYPE or the CKA_VALUE_LEN attribute).
RandomInfo client's and server's random data information
pReturnedKeyMaterial points to a CK_WTLS_KEY_MAT_OUT structure which receives the handles for the keys generated and the IV

CK_WTLS_KEY_MAT_PARAMS_PTR is a pointer to a CK_WTLS_KEY_MAT_PARAMS.
