mcrypt_list_algorithms — Get an array of all supported ciphers
mcrypt_list_algorithms() is used to get an array of all supported algorithms in the lib_dir parameter.
mcrypt_list_algorithms() takes an optional lib_dir parameter which specifies the directory where all algorithms are located. If not specifies, the value of the mcrypt.algorithms_dir php.ini directive is used.
Example#1 mcrypt_list_algorithms() Example
<?php
$algorithms = mcrypt_list_algorithms("/usr/local/lib/libmcrypt");
foreach ($algorithms as $cipher) {
echo "$cipher<br />\n";
}
?>
The above example will produce a list with all supported algorithms in the "/usr/local/lib/libmcrypt" directory.
