<para>
Get the md5 hash of a buffer. The result is put in the 16 bytes
buffer <parameter>digest</parameter>.
</para>
<para>
The MD5 algorithm takes as input a message of arbitrary length and
produces as output a 128-bit "fingerprint" or "message digest" of
the input. It is conjectured that it is computationally infeasible
to produce two messages having the same message digest, or to
produce any message having a given prespecified target message
digest. For more information see RFC 1321.</para>
