Welcome to RuffNekk's Crypto Pages. On this site you will find information, tools and software dealing with cryptology, in particular classic 'pencil and paper' cryptosystems.
Most of the cipher systems described on this site were all meant to be encoded and decoded with pencil and paper. They are often reffered to as 'field ciphers' because the agents in the field were supposed to be able to use them without any tools, machinery or computers. Most ciphers date back to eras where computers did not even exist.
The site also deals with other ciphers that use some kind of mechanical tool to encode or decode a message. A famous example is the Enigma machine.
The site is divided into various sections. You can use the menu below to proceed. To return to a previous menu you can use the header of each page, which will also inform you about where you are on the site.
I hope you enjoy the information and find it useful. Feel free to email me or sign my guestbook with any suggestions, remarks or corrections you deem neccesary. Have fun!
