Function Documentation

void hmac_md5 ( unsigned char * text,

int text_len,

unsigned char * key,

int key_len,

unsigned char * digest

)

RFC 2104 hmac_md5 function calculates a digest from a given data buffer and a given key.

Parameters:

text pointer to data stream

text_len length of data stream

key pointer to authentication key

key_len length of authentication key

digest caller digest to be filled in 128-bit

Returns:
