-#
-# Portable PHP password hashing framework.
-#
-# Version 0.3 / genuine.
-#
-# Written by Solar Designer <solar at openwall.com> in 2004-2006 and placed in
-# the public domain.  Revised in subsequent years, still public domain.
-#
-# There's absolutely no warranty.
-#
-# The homepage URL for this framework is:
-#
-#	http://www.openwall.com/phpass/
-#
-# Please be sure to update the Version line if you edit this file in any way.
-# It is suggested that you leave the main version number intact, but indicate
-# your project name (after the slash) and add your own revision information.
-#
-# Please do not change the "private" password hashing method implemented in
-# here, thereby making your hashes incompatible.  However, if you must, please
-# change the hash type identifier (the "$P$") to something different.
-#
-# Obviously, since this code is in the public domain, the above are not
-# requirements (there can be none), but merely suggestions.
