Besides the classical variant Beaufort ciphers and Autokey ciphers are supported as well. Transposition (Solve) Transposition ciphers are those where the original characters of the plaintext are rearranged according to a system or key to form the ciphertext. It is a digraphic substitution cipher, and uses four grids to match the digraphs from plaintext to ciphertext and vice versa. From my stance the main solvers here are Origins Wormy and Numskul123, as these two were practically the ones that got the German plaintext. This kind of ciphers are named like that because they proceed by substitute the input letters by always the same values during all the encryption process - unlike the polyalphabetical ciphers (such as Vigenere cipher for instance). • Enigma cipher with saveable settings.
