openssl_get_cipher_methods — Obtiene los métodos de cifrado disponibles
Obtiene una lista de los métodos de cifrado disponibles.
Un array de los métodos de cifrado disponibles.
Ejemplo #1 Ejemplo de openssl_get_cipher_methods()
Muestra qué pinta tienen los métodos de cifrado disponibles, y también qué alias podrían estar disponibles.
<?php
$cifrados = openssl_get_cipher_methods();
$cifrados_y_alias = openssl_get_cipher_methods(true);
$alias_cifrados = array_diff($cifrados_y_alias, $cifrados);
print_r($cifrados);
print_r($alias_cifrados);
?>El resultado del ejemplo sería algo similar a:
