What is a cipher code?

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. … Codes generally substitute different length strings of character in the output, while ciphers generally substitute the same number of characters as are input.

Is there an unbreakable cipher?

The only unbreakable cryptosystem known – the Vernam cipher. Of all the methods of encryption ever devised, only one has been mathematically proved to be completely secure. It is called the Vernam cipher or one-time pad. The worth of all other ciphers is based on computational security.
