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;




 
ulWordsizewordsize of RC5 cipher in bytes 


ulRoundsnumber 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;




 
ulWordsizewordsize of RC5 cipher in bytes 


ulRoundsnumber of rounds of RC5 encipherment 


pIvpointer to initialization vector (IV) for CBC encryption 


ulIvLenlength 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.
