Function Documentation

void hmac_md5 (  const u8 *  key, size_t  key_len, const u8 *  data, size_t  data_len, u8 *  mac )

HMAC-MD5 over data buffer (RFC 2104). Parameters: key  Key for HMAC operations key_len  Length of the key in bytes data  Pointers to the data area data_len  Length of the data area mac  Buffer for the hash (16 bytes) Definition at line 109 of file md5.c. Here is the call graph for this function:

void hmac_md5_vector (  const u8 *  key, size_t  key_len, size_t  num_elem, const u8 *  addr[], const size_t *  len, u8 *  mac )

HMAC-MD5 over data vector (RFC 2104). Parameters: key  Key for HMAC operations key_len  Length of the key in bytes num_elem  Number of elements in the data vector addr  Pointers to the data areas len  Lengths of the data blocks mac  Buffer for the hash (16 bytes) Definition at line 35 of file md5.c. Here is the call graph for this function:

void md5_vector (  size_t  num_elem, const u8 *  addr[], const size_t *  len, u8 *  mac )

MD5 hash for data vector. Parameters: num_elem  Number of elements in the data vector addr  Pointers to the data areas len  Lengths of the data blocks mac  Buffer for the hash Definition at line 141 of file md5.c.
