* sneak.php - v 1.27 - 2003/02/12
*
* SNEAK: Snarkles.Net Encryption Assortment Kit
* =============================================
* Send and decode messages using a number of different methods
*
* Please forward any suggestions, problems, improvements, etc. to the
* e-mail address below. Thanks! :D

/************************************************************************
* Changelog
* =========
* v 1.27 - 2004/10/28:
* - Added zero padding to hex conversions < 10. Thanks to bubuche93 for
* the heads up.
*
* v 1.26 - 2003/06/20:
* - Added function strip_spaces to remove spaces prior to trying to
* base64 decode a string. Thanks for Jeian and Goldfish for pointing
* this out.
*
* v 1.25 - 2003/02/12:
* - Fixed a bug in form that initially displayed an error about an
* undefined variable in the textbox if error_reporting is set to max.
* Thanks to Justin Hagstrom for notifying me of the problem. :)
*
* v 1.24 - 2003/02/01:
* - D'oh! Fixed a bug I introduced with the Caesar Bruteforce option that
* stuck that XSS vulnerability right back in there! :P
*
* v 1.23 - 2003/01/27:
* - Added "Caesar Bruteforce" option which will attempt all 26
* possible shifts of a Caesar (rotation) cipher.
*
* v 1.22 - 2003/01/26:
* - Textbox now retains original text value, so you can try different
* encryption methods on the same text without copying/pasting
* Thanks to barnseyboy who suggested the feature. :)
*
* v 1.21 - 2003/01/14:
* - Fixed XSS vulnerability that could potentially allow people to steal
* cookies from sites with the script installed.
* Credit for spotting this vulnerability goes to JeiAr from
* CyberArmy Security Research (http://www.security-research.org/)
*
* v 1.20 - 2002/08/10:
* - Added HTML entity encode/decode option
* - Changed order of listings so encoding is always before decoding
* - Fixed problem that caused special characters to be lost when
* writing back to the screen
*
* v 1.11 - 2002/02/21:
* - Cleaned up code some--now all chunk_splitting and str_replacing is
* done within the functions, rather than during the switch statement
* - Specified CRYPT_STD_DES in crypt() function, to fix problem with PHP 4.1.2
*
* v 1.10 - 2002/02/17:
* - Added bin2hex, hex2bin, and pig latin functions
*
* v 1.00 - 2002/02/15:
* - Nothing yet, but I'm sure that'll CHANGE. Ha! Get it? ;)
