Question

do you think there something exist like unbreakable code?
which any cipher couldn't decrypt ?​

Answer 1

Explanation:

This means that the same letter can be converted to two different letters by the cipher, making frequency analysis useless for cracking. The conditions for the Vernham cipher to be unbreakable include: using a random key only once, which is the same length or longer, than the plaintext.

A one-time pad is a set of random cipher tables, each designed to be used for just one message. In theory, this makes it unbreakable
