[raamdev]

It looks like defuse and RNCryptor are two alternatives that have replaced mcrypt, which has been abandonware for nearly a decade now. Mcrypt has been deprecated and will be removed from the core and in PECL in PHP 7.2.

[jaswrks]

I've worked with Defuse recently and there is an example here if it helps.
https://github.com/websharks/s2member/blob/dev/src/includes/classes/utils-defuse.inc.php

[jaswrks]

The trickiest part about Defuse is that it requires a Defuse-generated key that needs to be stored in the WP database once it is generated for a site; i.e., you can't just use any random string or wp_salt(). It requires a special key only Defuse can generate.

[jaswrks]

Generating the key.

use Defuse\Crypto\Key;
$key = Key::createNewRandomKey()->saveToAsciiSafeString();

Saving it in the DB.

update_option('defuse_key', $key);

Reading, unpacking the key.

$key = Key::loadFromAsciiSafeString(get_option('defuse_key'));

Using the key.

use Defuse\Crypto\Key;
use Defuse\Crypto\Crypto;

$key = Key::loadFromAsciiSafeString(get_option('defuse_key'));

$encrypted = Crypto::encrypt('something secret', $key, false);
$decrypted = Crypto::decrypt($encrypted, $key, false);
