Beschreibung
array mcrypt_module_get_supported_key_sizes ( string $algorithm [, string $lib_dir ] )
Returns an array with the key sizes supported by the specified algorithm.
If it returns an empty array then all key sizes between 1 and
mcrypt_module_get_algo_key_size() are supported by the
algorithm. The optional lib_dir
parameter can
contain the location where the mode module is on the system.
See also mcrypt_enc_get_supported_key_sizes() which is
