typedef struct CK_GCM_PARAMS { CK_BYTE_PTR pIv; CK_ULONG ulIvLen; CK_BYTE_PTR pAAD; CK_ULONG ulAADLen; CK_ULONG ulTagBits; } CK_GCM_PARAMS;
pIv | pointer to initialization vector |
ulIvLen | length of initialization vector in bytes. The length of the initialization vector can be any number between 1 and 256. 96-bit (12 byte) IV values can be processed more efficiently, so that length is recommended for situations in which efficiency is critical. |
pAAD | pointer to additional authentication data. This data is authenticated but not encrypted''.'' |
ulAADLen | length of ''pAAD'' in bytes. |
ulTagBits | length of authentication tag (output following cipher text) in bits. Can be any value between 0 and 128. |
CK_GCM_PARAMS_PTR is a pointer to a CK_GCM_PARAMS.
typedef struct CK_CCM_PARAMS { CK_ULONG ulDataLen; /*plaintext or ciphertext*/ CK_BYTE_PTR pNonce; CK_ULONG ulNonceLen; CK_BYTE_PTR pAAD; CK_ULONG ulAADLen; CK_ULONG ulMACLen; } CK_CCM_PARAMS;
ulDataLen | length of the data where 0 <= ''ulDataLen'' < 28L. |
pNonce | the nonce. |
ulNonceLen | length of ''pNonce'' (<= 15-L) in bytes. |
pAAD | Additional authentication data. This data is authenticated but not encrypted. |
ulAADLen | length of ''pAuthData'' in bytes. |
ulMACLen | length of the MAC (output following cipher text) in bytes. Valid values are 4, 6, 8, 10, 12, 14, and 16. |
CK_CCM_PARAMS_PTR is a pointer to a CK_CCM_PARAMS.
