Cipher Definition
Cipher refers to an algorithm that assists in executing encryption or decryption. It allows one to change a plain text to unreadable form or changing unreadable text to readable text by human beings (Stinson 134).
Difference between cipher and code
There are several differences that exist between a cipher and a code. Firstly, codes are easily computable thus are very fast. On the other hand, ciphers take much time to compute or rather they are non-computable hence end up being slower that the codes. Secondly, ciphers depend on a key since they are generated using a given key. However, codes do not ...
