Generally, a good starting point would be to start with the most common and well known classical ciphers, eliminate those that obviously don't fit, and try the remaining ones to see if any of them might work.

WebbThe Atbash Cipher is a really simple substitution cipher that is sometimes called mirror code. It is believed to be the first cipher ever used, and its use pre-dates Egyptian examples of encryption. To use Atbash, you simply reverse the alphabet, so A encodes to Z, B to Y and so on. Atbash is considered a special case of Affine Cipher, a ... Webb27 maj 2024 · This cipher is more secure than simple substitution, but is still susceptible to ciphertext-only attacks by doing statistical frequency counts of pairs of letters, since each pair of letters always gets encrypted in the same fashion.
