mcrypt is deprecated, what is the alternative?

It’s best practice to hash passwords so they are not decryptable. This makes things slightly more difficult for attackers that may have gained access to your database or files.

If you must encrypt your data and have it decryptable, a guide to secure encryption/decryption is available at https://paragonie.com/white-paper/2015-secure-php-data-encryption. To summarize that link:

  • Use Libsodium – A PHP extension
  • If you can’t use Libsodium, use defuse/php-encryption – Straight PHP code
  • If you can’t use Libsodium or defuse/php-encryption, use OpenSSL – A lot of servers will already have this installed. If not, it can be compiled with –with-openssl[=DIR]
