La première syntaxe utilise libmcrypt 2.2.x, et la seconde
|
|
libmcrypt 2.4.x ou plus récent.

Il est plus intéressant d'utiliser la fonction
|
|
<function>mcrypt_enc_get_key_size</function> sachant qu'elle utilise la ressource
|
|
retournée par la fonction <function>mcrypt_module_open</function>.

L'exemple ci-dessus montre l'utilisation de la fonction

lorsqu'elle a été compilée avec la bibliothèque

2.4.x ou 2.5.x.
