int | hmac (const char *buffer, int buffer_length, const char *key, int key_length, unsigned char *digest, int digest_len, int block_size, void(*hash_func)(const char *, int, unsigned char *)) |
Generate HMAC. | |
int | hmac_md5 (const char *buffer, int buffer_length, const char *key, int key_length, unsigned char digest[MD5_DIGEST_LENGTH]) |
Generate HMAC using md5 hash function Note that this function produces a digest in binary form which must be converted to a human readable form with md5_string. | |
int | hmac_sha1 (const char *buffer, int buffer_length, const char *key, int key_length, unsigned char digest[SHA1_DIGEST_LENGTH]) |
Generate HMAC using sha1 hash function Note that this function produces a digest in binary form which must be converted to a human readable form with sha1_string. |
