What is a substition cipher?

A substition cipher is one of the most simple ciphers. Each letter of the alphabet is replaced with a random letter, and the message is encoded. Note that a letter cannot be encoded to itself!

Tips for solving

  • Letter frequency: E is the most common letter in the English language, followed by T A O I N
  • Common words: Try to look for common words like THE, TO, IN, IT, IS, and so on
  • Cribs: With a few characters, guessing the entire word may be possible. This is called finding a "crib." Example: Given P E _ P _ E, we can reasonably guess this word to be PEOPLE and solve a few letters

Features

  • Over 5,000 unique quotes
  • Two modes: Aristocrat ciphers (words with spaces) and Patristocrat ciphers (letters in groups of five)
  • Keep track of your speed with a built-in timer

Put your cryptography skills up to the test with Cipher Cracker!

Please add more difficult ciphers like maybe Vigenere where you have to do a Kappa Test!

Very Cool. Where did you get the quotes from? Also as a suggestion for future improvement it is not very mobile-friendly. I appreciate that you used hashes in this project, as they are cool.
