Introduction

Ces fonctions permettent d'accéder à la bibliothèque mcrypt, qui dispose d'une grande variété d'algorithmes de chiffrement, tels DES, TripleDES, Blowfish (par défaut), 3-WAY, SAFER-SK64, SAFER-SK128, TWOFISH, TEA, RC2 et GOST en modes CBC, OFB, CFB et ECB. De plus, elles acceptent aussi RC6 et IDEA qui sont considérés comme "non-libres". CFB/OFB est sur 8bit par défaut.

This extension rely in libmcrypt which is dead, unmaintained since 2007.

Please don't rely on it, consider switching to well maintained alternatives (openssl, crypt, password hashing functions, phpseclib, password_compat...)

if you get a "The mcrypt extension is missing" alert somewhere, use
"sudo php5enmod mcrypt" and restart your server to enable it.

In linux systems,mcrypt is necessary for installing CMSes like majento. First You need to install the mcrypt library.

If using a Debian-based Linux system, you can run the following commands:

  sudo apt-get install php5-mcrypt

then restart the apache server

  sudo /etc/init.d/apache2 restart
