Manual
mcrypt_module_get_supported_key_sizes(
string$algorithm,
[string$lib_dir] ): array
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.
Parameters
- algorithm
-
The algorithm to be used.
- lib_dir
-
The optional lib_dir parameter can contain the location where the algorithm module is on the system.
Return Values
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.
