mcrypt Library for PHP
This section describes the mcrypt library - encryption extension for PHP. mcrypt supports DES and many other encryption algorithms.
"mcrypt" is the suggested encryption extension for PHP. It supports a wide variety of block algorithms
such as DES, TripleDES, Blowfish (default), 3-WAY, SAFER-SK64, SAFER-SK128, TWOFISH, TEA, RC2
and GOST in CBC, OFB, CFB and ECB cipher modes. See
http://sourceforge.net/projects/mcrypt for details.
The best way to download and install "mcrypt" for your Windows system is to download
the pre-compiled "mcrypt" version by the steps below:
1. Go to http://ftp.emini.dk/pub/php/win32/mcrypt/.
2. Download the binary file, libmcrypt.dll, 19-Jan-2004 02:27, 163k.
3. Save libmcrypt.dll to your PHP directory, like \php\.
4. Open PHP initialization file, \php\php.ini.
5. Uncomment line "extension=php_mcrypt.dll".
You are ready to use "mcrypt" encryption functions.
