  • Kenny Code - Converts text Kenny Code.
  • Keyed Caesar Cipher - The Keyed Caesar cipher is a variation to the standard Caesar cipher (shifting the letters by 13). In a keyed version, the alphabet is "keyed" by using a word and those letters are moved to the front of the alphabet and the rotation is performed.

  • Porta Key Cipher - This cipher is a polyalphabetic substitution cipher.
  • Polybius Square Cipher - This cipher is a polyalphabetic substitution cipher.
  • Rail Fence Cipher - Tool to convert text using the rail fence cipher.
  • Rotation Cipher - Also known as a caesar cipher, this allows you to rotate numbers (Rot 5), letters (Rot 13), letters and numbers (Rot 18), all ASCII characters (Rot 47), or show all rotations from 0 to 25 either encrypted or decrypted.
  • Route Transposition Cipher - The route transposition cipher rearranges the plaintext letters based on a shape of an imaginary path drawn on a grid, which contains all the message letters.
  • Running Key Cipher - This cipher is a polyalphabetic substitution cipher.
  • Slash and Pipe Code - Substitution cipher using the characters \ | /.
  • Straddle Checkerboard Cipher - Substitution cipher using a variable length alphabet.
  • Substitution Cipher - Allows you to create your own version of an alphabet as a substitution.
  • Tap (Knock) Code - Converts characters between letters, numbers and dots via a polybius square.
  • Tomtom Code - Substitution cipher using the characters \ | /.
  • Trifid Cipher - The Trifid cipher uses three tables to fractionate letters into trigrams, mixes the parts of the trigrams and then uses the table to convert the trigrams back to letters again.
  • T9 Code Solver - Tool to solve the phone pad's T9 code using a large dictionary.
