✧ Caesar cipher ✧

A Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or the Caesar shift, is one of the simplest and most widely known encryption techniques in cryptography. Named after Julius Caesar, who is said to have used it, it is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed numbe...

What other places are Vigenère ciphers actually used? I have only seen them used in CTF challenges. I'm considering adding it to Ronin::Support::Crypto to check that box and help CTF players; but it annoys me that I'm adding code for something that is primarily used in CTF challenges.

#vigenere is a #publicdomain example #OpenSSL provider.

vigenere is an implementation of an extended Vigenère cipher that is used as an OpenSSL provider. The simple (and insecure) Vigenère cipher is chosen to minimize obscuring how OpenSSL providers work. The example shows the various components and methods a provider must implement using the cipher.
