I'm not "Completely" Finished with my decryptor/encryptor coded from scratch but you can play with it and see if you find any patterns.

The cookie value might be a MD5 hash which is impossible to reverse engineer unfortunately. http://www.spitzner.net/md5.html

Decryptor/Encryptor

This is my first time playing with number systems so i decided to write this tool that encrypts/decrypts * String(No White Space ASCII*2) The string can be decimal,binary,base*2,base64,text. If you dont know about BASE number systems i would definately read up on this before using this. After im finished this i will be writing another one that does the same thing for any text, paragraph, etc. To use the tool you input a string in the top blank. You select what the strings current base is with the first dropdown box and select what you would like to translate it into with the second dropdown box. You then hit submit and it will show you the results.

Like i said im not completely finished because i wrote this from scratch and some things are still a little b***y but for the most part it works. I am also writing my own algorithm to encrypt and decrypt passwords. It will appear as a selection when im finished also. Its open for s***estions...

Everything that i have coded should work right. Please let me know if something doesnt convert right and post the example here.

PS: WHITE SPACE = Decimal Value *2 = BINARY *00000.... white space will make a difference in the conversion equations~
