+HMAC, HMAC_Init, HMAC_Update, HMAC_Final - HMAC message authentication code

+=head1 SYNOPSIS

+ int key_len, const unsigned char *d, int n,
+ unsigned char *md, unsigned int *md_len);

+
+ void HMAC_cleanup(HMAC_CTX *ctx);
+
+=head1 DESCRIPTION
+
+HMAC is a MAC (message authentication code), i.e. a keyed hash
+function used for message authentication, which is based on a hash
+function.
+
+HMAC() computes the message authentication code of the B<n> bytes at
+B<d> using the hash function B<evp_md> and the key B<key> which is
+B<key_len> bytes long.
+
+It places the result in B<md> (which must have space for the output of
+the hash function, which is no more than B<EVP_MAX_MD_SIZE> bytes).
+If B<md> is NULL, the digest is placed in a static array. The size of
+the output is placed in B<md_len>, unless it is B<NULL>.
+
+B<evp_md> can be EVP_sha1(), EVP_ripemd160() etc.
+B<key> and B<evp_md> may be B<NULL> if a key and hash function have
+been set in a previous call to HMAC_Init() for that B<HMAC_CTX>.
+
+HMAC_cleanup() erases the key and other data from the B<HMAC_CTX>.
+
+The following functions may be used if the message is not completely
+stored in memory:
+
+HMAC_Init() initializes a B<HMAC_CTX> structure to use the hash
+function B<evp_md> and the key B<key> which is B<key_len> bytes long.
+
+HMAC_Update() can be called repeatedly with chunks of the message to
+be authenticated (B<len> bytes at B<data>).
+
+HMAC_Final() places the message authentication code in B<md>, which
+must have space for the hash function output.
+
+=head1 RETURN VALUES
+
+HMAC() returns a pointer to the message authentication code.

+
+MD2 and MD5 are cryptographic hashs function with a 128 bit output.
+
+MD2() and MD5() compute the MD2 and MD5 message digest of the B<n>

+
+MD2_Final() places the message digest in B<md>, which must have space

+
+MD5_Init(), MD5_Update() and MD5_Final() are analogous using an
