mcrypt_module_get_supported_key_sizes
(PHP 4 >= 4.0.2, PHP 5)
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.
Parameters
-
algorithm -
The algorithm to be used.
-
lib_dir -
The optional
lib_dirparameter 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.

A small bit of php for listing available encryption algorythms and their keysizes.
<?php
$cipher_dir = "/usr/local/lib/libmcrypt";
$algorithms = mcrypt_list_algorithms($cipher_dir);
echo "<html><head></head><body><table><tr>\n";
foreach ($algorithms as $cipher) {
echo "<td>" . $cipher . "</td><td>";
$ksizes = mcrypt_module_get_supported_key_sizes($cipher, $cipher_dir);
if($ksizes==NULL) echo mcrypt_module_get_algo_key_size($cipher, $cipher_dir);
else foreach ($ksizes as $size) {
echo $size . " ";
}
echo "</td></tr>\n";
}
echo "</table></body></html>\n";
?>
I hope some one finds it handy.
