(PHP 4 >= 4.0.2, PHP 5)

mcrypt_module_get_supported_key_sizes — Returns an array with the supported keysizes of the opened algorithm

### Descripción

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 used on open encryption modules.
