# PBKDF2 Module

> Eggdrop encrypts its userfile, so users can have secure passwords. Eggdrop will not start without an encryption module.

> As of Eggdrop 1.9.0, a new encryption module was added, the PBKDF2 module. The PBKDF2 module was designed to work with the previous encryption module (blowfish) to make the transition easier. If this is a new bot, you can safely load just the PBKDF2 module. If you are transitioning a userfile from 1.8 or earlier, you should load this AND the blowfish module. By doing so, Eggdrop will seamlessly update the old blowfish hashes to the new PBKDF2 hashes once a user logs in for the first time, and allow you to (eventually) remove the blowfish module altogether.

> Outside of the specific case noted above, please note that if you change your encryption method later (i.e. using other modules like a rijndael module), you can’t use your current userfile anymore.

> Put this line into your Eggdrop configuration file to load the server module::

>   loadmodule pbkdf2

There are also some variables you can set in your config file:

> set pbkdf2-method “SHA256”

>   Cryptographic hash function used. Use `openssl list -digest-algorithms` to view all available options

> set pbkdf2-rounds 1600

>   Number of rounds. The higher the number, the longer hashing takes; but also generally the higher the protection against brute force attacks.

> This module requires: none
