* *
* JAVACRYPT: CLIENT-SIDE crypt(3) USING JAVASCRIPT *
* *
***************************************************************
* Original: Jeff Walden (Jswalden86@netzero.net ) *
* modified 2003 by Franc,ois Pirsch *
* *
* This Javascript allows you to calculate the encrypted *
* password generated by the UNIX function crypt(3) on your *
* computer without using an online script in PHP, PERL, *
* shell, or any other server-side script. The only changes *
* you need make in this are in function dP(), which is right *
* below the end of this comment. Refer to the directions *
* there for details. *
* *
* I wish I could take full credit for this script, but there *
* are several people who deserve most of the credit *
* *
* First and foremost, I thank John F. Dumas for writing *
* jcrypt.java, a Java-based implementation of crypt(3) and *
* from which this Javascript is heavily based (actually, I *
* just did a direct port from his code, using Sun's tutorial *
* and my knowledge of Javascript). I additionally thank *
* Eric Young for writing the C code off which Dumas based *
* his script. Finally, thanks goes to the original writers *
* of crypt(3), whoever they are. *
* *
* If you have questions, I suggest you ask John Dumas about *
* them, as I have no real idea what any of this code does. *
* Base the questions off his source code, as Javascript and *
* Java are (in basic operators) nearly identical. *
* *
* jcrypt.java source code can be found at: *
* http://locutus.kingwoodcable.com/jfd/crypt.html *
