The function HashPassword() generates an eight-character random salt for each password, encoding the salt into the returned hash value. Regarding salts, phpass takes care of the complexity of adding salt to hashes. phpass utilizes iterations and salt regardless of which algorithm is utilized. If using PHP 5.3.0 or later with the Suhosin patch, phpass has the ability to hash with blowfish (CRYPT_BLOWFISH in PHP), falling back to DES hashes if using PHP 5.3.0 and no Suhosin patch (CRYPT_EXT_DES in PHP), and a final fallback to salted MD5 based hashes (known as portable hashes). Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies Ubuntu 10.04 Server LTS (released 24 April 2010): Suhosin has unfortunately not been well maintained, so Debian and other distributions are removing its support. Note that Debian is considering removing Suhosin patched PHP from their distribution, so future patching may be required ( http :// lwn. Red Hat Enterprise Linux 5 and 6 and likewise CentOS 5 and 6 do not include this patch by default and it must be compiled manually for those distributions ( http :// biz / faq / rhel – linux – install – suhosin – php – protection /). Ubuntu and Debian Linux include the Suhosin PHP patch via the package php5-suhosin. Specifically recommended is PHP 5.3.0 or later with the Suhosin security hardening patch (). This is because particular PHP algorithm code is only included in 5.3.0 and later. To obtain the highest level of security with phpass, the server must be running PHP version 5.3.0 or later. – Iterations or password stretching (a specified number of iterations or rounds set as desired) – Salt (random unique salt generated for each password) – Hash algorithm (blowfish, DES, or MD5 in that order if available) Phpass utilizes three components for password hashing:
