mcrypt_get_key_size
Description
int mcrypt_get_key_size ( int cipher )int mcrypt_get_key_size ( string cipher, string module )
- The first prototype is when linked against libmcrypt 2.2.x, the second when linked against libmcrypt 2.4.x or 2.5.x.
- mcrypt_get_key_size() is used to get the size of a key of the specified cipher (in combination with an encryption mode).
- 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 mcrypt_enc_get_key_size() function as this uses the resource returned by mcrypt_module_open().
