openssl_get_cipher_methods

(PHP 5 >= 5.3.0)

openssl_get_cipher_methodsGets available cipher methods

Description

array openssl_get_cipher_methods ([ bool $aliases = false ] )

Gets a list of available cipher methods.

Parameters

aliases

Set to TRUE if cipher aliases should be included within the returned array.

Return Values

An array of available cipher methods.

Examples

Example #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);

?>

The above example will output something similar to:
