The Typologically Different Question Answering Dataset

In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with "code", as they are both a set of steps that encrypt a message; however, the concepts are distinct in cryptography, especially classical cryptography.

What is the difference between ciphers and codes?

  • Ground Truth Answers: cipher" is synonymous with "code

  • Prediction:

Codes generally substitute different length strings of characters in the output, while ciphers generally substitute the same number of characters as are input.  There are exceptions and some cipher systems may use slightly more, or fewer, characters when output versus the number that were input.
