RSA Security 5 manual AISignVerify, Pointer to a Bsignverifyparams structure

AI_SignVerify

AI_SignVerify

Purpose:

This AI allows you to sign a message in compliance with the X9.31 standard, or to verify X9.31 compliant signatures.

Type of information this allows you to use:

an RSA private key to sign a message in compliance with the X9.31 standard, or an RSA public key to verify X9.31 compliant signatures. To be fully compliant with the X9.31 standard, use only keys that are generated by AI_RSAStrongKeyGen.

Format of info supplied to B_SetAlgorithmInfo:

a pointer to a B_SIGN_VERIFY_PARAMS structure:

typedef struct {				/* Current Choices */
unsigned char *encryptionMethodName;			/* “rsaSignX931”, “rsaVerifyX931” */
POINTER	encryptionParams; /* Null for what is currently available*/
unsigned char *digestMethodName;				/* “sha1” */
POINTER	digestParams;			/* Null for sha1 */
unsigned char *formatMethodName;				/*”formatX931” */
POINTER	formatParams; /* structure of type A_X931_PARAMS for sha1 */
} B_SIGN_VERIFY_PARAMS;
Set the arguments for B_SIGN_VERIFY_PARAMS as follows:
Argument		Values		Comments
encryptionMethodName		rsaSignX931
		rsaVerifyX931
encryptionParams		Null Pointer for
		RSA X9.31
digestMethodName		sha1
digestParams		Null Pointer for
		SHA1
