一小段用于列出可用加密算法及其密钥大小的 php 代码。
<?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";
?>
希望有人觉得它很方便。
