Default Re: "Unbreakable Codes"?

Any type of "one-time pad" (also known as a Vernan cipher) is mathematically unbreakable, although in practice they are often unwieldly to use, at least viz conventional digital cryptography. Quantum cryptography promises to make Vernan ciphers much more widely used, but I'm not certain how *realistic* that type of technology is for now..

Launch codes for nukes are traditionally protected using a Vernan cipher (along w/ other types of extremely sensitive information).
