The comment above by ynniv@dev.null ( cc.gatech.edu ) on 6 June 2002 is incorrect. The word 'encryption' does *not* imply something can or should be undone. The encryption used in traditional unix password and shadow files is one way encryption and there's a good reason why it isn't commonly referred to as one way hashing. I have yet to find a security book that doesn't consider one way encryption as encryption at all. The selection between one way encryption and two way encryption (or reversible and irreversible encryption if you prefer) are dependent upon the needs of those implementing the security model. It is my humble opinion that both this post and the one above by ynniv@dev.null ( cc.gatech.edu ) from 6 June 2002 above should both be removed as they are essentially noise and don't really contribute to the documentation of the md5 function or it's practial uses at all. -- http://www.php.net/manual/en/function.md5.php http://master.php.net/manage/user-notes.php?action=edit+22738 http://master.php.net/manage/user-notes.php?action=delete+22738 http://master.php.net/manage/user-notes.php?action=reject+22738
