int mcrypt_module_get_algo_key_size ( string algorithm [,
string lib_dir])
This function returns the maximum supported key size of the algorithm specified in bytes. The optional lib_dir parameter can contain the location where the mode module is on the system.

(PHP 4 >= 4.0.2)
mcrypt_module_get_supported_key_sizes -- Returns an array
with the supported keysizes of the opened algorithm
Description
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.
