RSA Security manual AIMD5WithRC2CBCPadBER

AI_MD5WithRC2_CBCPad

Format of info supplied to B_SetAlgorithmInfo:

pointer to a B_RC2_PBE_PARAMS structure:

typedef struct {
unsigned int	effectiveKeyBits;	/* effective key size in bits */
unsigned char	*salt;	/* pointer to 8-byte salt value */
unsigned int	iterationCount;	/* iteration count */

} B_RC2_PBE_PARAMS;

This algorithm will accept a maximum of 1024 effective key bits for domestic use and 40 effective key bits for export. RSA Security Inc. recommends a minimum iteration

count of 1,000. However, for an additional byte or two of security the iteration should be 28 to 216.

Format of info returned by B_GetAlgorithmInfo:

pointer to a B_RC2_PBE_PARAMS structure (see above).

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_MD5 and AM_RC2_CBC_ENCRYPT for encryption or AM_RC2_CBC_DECRYPT for

decryption.

Key info types for keyObject in B_EncryptInit or B_DecryptInit:

KI_Item that gives the password.

Compatible representation:
