RC2 mechanism parameters

CK_RC2_PARAMS; CK_RC2_PARAMS_PTR

CK_RC2_PARAMS provides the parameters to the CKM_RC2_ECB and CKM_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;

CK_RC2_PARAMS_PTR is a pointer to a CK_RC2_PARAMS.

CK_RC2_CBC_PARAMS; CK_RC2_CBC_PARAMS_PTR

CK_RC2_CBC_PARAMS is a structure that provides the parameters to the CKM_RC2_CBC and CKM_RC2_CBC_PAD mechanisms. It is defined as follows:

typedef struct CK_RC2_CBC_PARAMS {
CK_ULONG ulEffectiveBits;
CK_BYTE iv[8];
} CK_RC2_CBC_PARAMS;

ulEffectiveBits	the effective number of bits in the RC2 search space
iv	the initialization vector (IV) for cipher block chaining mode

CK_RC2_CBC_PARAMS_PTR is a pointer to a CK_RC2_CBC_PARAMS.

CK_RC2_MAC_GENERAL_PARAMS; CK_RC2_MAC_GENERAL_PARAMS_PTR

CK_RC2_MAC_GENERAL_PARAMS is a structure that provides the parameters to the CKM_RC2_MAC_GENERAL mechanism. It is defined as follows:

typedef struct CK_RC2_MAC_GENERAL_PARAMS {
CK_ULONG ulEffectiveBits;
CK_ULONG ulMacLength;
} CK_RC2_MAC_GENERAL_PARAMS;

ulEffectiveBits	the effective number of bits in the RC2 search space
ulMacLength	length of the MAC produced, in bytes

CK_RC2_MAC_GENERAL_PARAMS_PTR is a pointer to a CK_RC2_MAC_GENERAL_PARAMS.
