+/**
+ *
+ * Portable PHP password hashing framework.
+ *
+ * Originally written by Solar Designer <solar at openwall.com> in 2004-2006
+ *
+ * Modernized by Hautelook at https://github.com/hautelook/phpass
+ *
+ * Slightly repacked by Ozh to extend compatibility from PHP 5.3 to 7.1 in a single file
+ *
+ * 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.
