AI_DES_CBCPadIV8
AI_DES_CBCPadIV8
Purpose:
This AI allows you to perform DES encryption or decryption in CBC mode with an 8- byte initialization vector on data that is of any byte length. The padding mode is PKCS #5, which makes the ciphertext 1 to 8 bytes longer than the plaintext. See AI_DES_CBC_IV8 for the same algorithm type with no padding. See AI_DES_CBCPadBER for the same algorithm type with BER encoding.
Type of information this allows you to use:
an
Format of info supplied to B_SetAlgorithmInfo:
pointer to an unsigned char array that holds the 8 bytes of the initialization vector.
Format of info returned by B_GetAlgorithmInfo:
pointer to an unsigned char array that holds the 8 bytes of the initialization vector.
Crypto-C procedures to use with algorithm object:
B_EncryptInit, B_EncryptUpdate, B_EncryptFinal, B_DecryptInit,
B_DecryptUpdate, and B_DecryptFinal. You may pass (B_ALGORITHM_OBJ)NULL_PTR for all randomAlgorithm arguments.
Algorithm methods to include in application’s algorithm chooser:
AM_DES_CBC_ENCRYPT for encryption and AM_DES_CBC_DECRYPT for decryption.
Key info types for keyObject in B_EncryptInit or B_DecryptInit:
KI_DES8Strong, KI_DES8, KI_8Byte, KI_Item (if the length of the ITEM is 8), or KI_DES_BSAFE1.
