According to "Hakin9", [ 2] CrypTool is worldwide the most widespread e-learning software in the field of cryptology. [ 3][ 4] CrypTool implements more than 400 algorithms. [ 5]
Caesar cipher. The action of a Caesar cipher is to replace each plaintext letter with a different one a fixed number of places down the alphabet. The cipher illustrated here uses a left shift of 3, so that (for example) each occurrence of E in the plaintext becomes B in the ciphertext. In cryptography, a Caesar cipher, also known as Caesar's ...
