#AB CIPHER DECODER CODE#
Spirit DVD Code - The Mars rover has a DVD with a code printed around the perimeter. Rot13 - Swap letters from the beginning of the alphabet with the letters at the end of the alphabet. Pigpen - Old substitution cipher, said to be used by Hebrew rabbis and the Knights Templar. Morse Code - Once used to transmit messages around the world, this system can still be used in certain situations to send messages effectively when alternate mediums are not available. A simple replacment method that is usually the first one taught to children and is still an effective way to obscure your message. Letter Numbers - Replace each letter with the number of its position in the alphabet. Lego Bionicle - Different letter sets used in the Lego Bionicle world. Gold Bug - A substitution cipher from an Edgar Allan Poe short story. At most, you will select an alphabet, possibly key it, and maybe select an option for how the algorithm works.Īmerican Sign Language - These are the hand signs one uses to finger spell when a more advanced sign isn't known.Ītbash - A very simplistic cipher where you change A to Z, B to Y, and so on.īase64 - This is typically used to make binary data safe to transport as strictly text.īinary - Encode letters in their 8-bit equivalents.ĭancing Men - Sherlock Holmes solved a mystery that used a stick man cipher.įlag Semaphore - Signaling messages using flags, often from ship to ship. This is the most basic way to hide a message because the translation of the letter doesn't ever change. Replaces a letter with another letter or a set of symbols. If you know of another cipher that you think should be on here or a tool that would be useful, request it and perhaps it can be added to the site. This is a page dedicated to simple text manipulation tools, which all can be replicated with just paper and pencil. If the message isn't that important or if it is intended to be decrypted by hand, you should use a simpler tool. You can use a full-blown encryption tool, such as PGP. Let's say that you need to send your friend a message, but you don't want another person to know what it is.
