RC5 mechanism parameters

CK_RC5_PARAMS; CK_RC5_PARAMS_PTR

CK_RC5_PARAMS provides the parameters to the CKM_RC5_ECB and CKM_RC5_MAC mechanisms. It is defined as follows:

typedef struct CK_RC5_PARAMS {
CK_ULONG ulWordsize;
CK_ULONG ulRounds;
} CK_RC5_PARAMS;

ulWordsize	wordsize of RC5 cipher in bytes
ulRounds	number of rounds of RC5 encipherment

CK_RC5_PARAMS_PTR is a pointer to a CK_RC5_PARAMS.

CK_RC5_CBC_PARAMS; CK_RC5_CBC_PARAMS_PTR

CK_RC5_CBC_PARAMS is a structure that provides the parameters to the CKM_RC5_CBC and CKM_RC5_CBC_PAD mechanisms. It is defined as follows:

typedef struct CK_RC5_CBC_PARAMS {
CK_ULONG ulWordsize;
CK_ULONG ulRounds;
CK_BYTE_PTR pIv;
CK_ULONG ulIvLen;
} CK_RC5_CBC_PARAMS;

ulWordsize	wordsize of RC5 cipher in bytes
ulRounds	number of rounds of RC5 encipherment
pIv	pointer to initialization vector (IV) for CBC encryption
ulIvLen	length of initialization vector (must be same as blocksize)

CK_RC5_CBC_PARAMS_PTR is a pointer to a CK_RC5_CBC_PARAMS.

CK_RC5_MAC_GENERAL_PARAMS; CK_RC5_MAC_GENERAL_PARAMS_PTR

CK_RC5_MAC_GENERAL_PARAMS is a structure that provides the parameters to the CKM_RC5_MAC_GENERAL mechanism. It is defined as follows:

typedef struct CK_RC5_MAC_GENERAL_PARAMS {
CK_ULONG ulWordsize;
CK_ULONG ulRounds;
CK_ULONG ulMacLength;
} CK_RC5_MAC_GENERAL_PARAMS;

ulWordsize	wordsize of RC5 cipher in bytes
ulRounds	number of rounds of RC5 encipherment
ulMacLength	length of the MAC produced, in bytes

CK_RC5_MAC_GENERAL_PARAMS_PTR is a pointer to a CK_RC5_MAC_GENERAL_PARAMS.
