I'm wondering about different types of ciphers and their security. Specifically, I want to know which cipher is considered to be unbreakable. I'm looking for a cipher that, when used correctly, cannot be decrypted by unauthorized individuals.

When these conditions are met, the Vigenère cipher transforms into a one-time pad.

A one-time pad is considered a theoretically unbreakable cipher.
