WebJul 24, 2006 · ROT13 is a monoalphabetic substitution cipher, these ciphers are very easy to decrypt, e.g. by frequency analysis. The namespace System.Security.Cryptography in .NET 2.0 does not implement the ROT13 cipher, I had to implement my own method. While I developed my program, I became intrigued with the binary data. WebNov 20, 2012 · In particular, that is one example of an algorithm that tests the ciphertext and tells YES if it is ROT13/Base64 (or NO if it isn't). @fgrieu: technically, ROT13 is a cypher, albeit a very weak one. It is a Caesar cypher with a key (=shift) of 13. The problem being that the key is not really a secret. Both of them are encoding methods.
