Ciphers without keys
WebThe easiest keyless/shiftless method consists of testing all shifts, if the alphabet has 26 letters, it takes only 25 tries (dCode does it automatically). What are the variants of the Caesar cipher? Caesar cipher is best known with a shift of 3, all other shifts are possible. Some shifts are known with other cipher names.

WebDouble Transposition Cipher Decoder and Encoder. The double columnar transposition cipher is considered one of the most secure ciphers that can be performed by hand. It is equivalent to using two columnar transposition ciphers, with same or different keys. During World War I and II, it was used by various agents and military forces. Webcipher, any method of transforming a message to conceal its meaning. The term is also used synonymously with ciphertext or cryptogram in reference to the encrypted form of the message.

WebIt remained unbreakable for almost three centuries until 1863 when Friedrich Kasiski published a general method of deciphering Vigenère ciphers. You can use the link above to encode and decode text with Vigenère cipher if you know the key. The calculator below is different. It actually tries to break the Vigenère cipher using text statistics.
WebIn this paper, we propose related-key differential distinguishers based on the complementation property of Feistel ciphers. We show that with relaxed requirements on the complementation, i.e. the property does not have to hold for all keys and the complementation does not have to be on all bits, one can obtain a variety of … WebA null cipher, also known as concealment cipher, is an ancient form of encryption where the plaintext is mixed with a large amount of non-cipher material.
