Приклади

Приклад #1 openssl_get_cipher_methods() example

Shows how the available ciphers might look, and also which aliases might be available.

<?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);

?>

Наведений вище приклад виведе щось подібне до:
