(PHP 5 >= 5.3.0)

openssl_get_cipher_methods利用可能な暗号メソッドを取得

説明

array openssl_get_cipher_methods ([ bool $aliases = false ] )

利用可能な暗号メソッドの一覧を取得します。

パラメータ

aliases

返される array に暗号のエイリアスを含めるべき場合、 TRUE に設定します

返り値

利用可能な暗号メソッドの array

例1 openssl_get_cipher_methods() の例

どのように利用可能な暗号が見るか、およびどのエイリアスが利用可能か示します。

<?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);

?>

上の例の出力は、 たとえば以下のようになります。
