<para>
|
|
Calculates the MD5 hash of <parameter>str</parameter> using the
|
|
<ulink url="&url.rfc;1321">RSA Data Security, Inc.
|
|
MD5 Message-Digest Algorithm</ulink>, and returns that hash.
|
|
The hash is a 32-character hexadecimal number. If the optional
|
|
<parameter>raw_output</parameter> is set to &true;, then the md5 digest
|
|
is instead returned in raw binary format with a length of 16.
