Exemples

Exemple #1 Exemple openssl_get_cipher_methods()

Montre à quoi ressemblent les ciphers disponibles, ainsi que les alias disponibles.

<?php
$ciphers             
openssl_get_cipher_methods();
$ciphers_and_aliases openssl_get_cipher_methods(true);
$cipher_aliases      array_diff($ciphers_and_aliases$ciphers);

print_r($ciphers);

print_r($cipher_aliases);

?>

L'exemple ci-dessus va afficher quelque chose de similaire à :
