Created May 17, 2013 10:59 — forked from dzuelke/bcrypt.php
<?php
// secure hashing of passwords using bcrypt, needs PHP 5.3+
// see http://codahale.com/how-to-safely-store-a-password/
// salt for bcrypt needs to be 22 base64 characters (but just [./0-9A-Za-z]), see http://php.net/crypt
// just an example; please use something more secure/random than sha1(microtime) :)
$salt = substr(str_replace('+', '.', base64_encode(sha1(microtime(true), true))), 0, 22);
// 2a is the bcrypt algorithm selector, see http://php.net/crypt
