The first prototype is when linked against libmcrypt 2.2.x, the

<function>mcrypt_get_key_size</function> is used to get the size

of a key of the specified <parameter>cipher</parameter> (in

This example shows how to use this function when linked against libmcrypt
|
|
2.4.x and 2.5.x. It is more useful to use the
|
|
<function>mcrypt_enc_get_key_size</function> function as this uses the
|
|
resource returned by <function>mcrypt_module_open</function>.
