Even one-time pads, actually, to some extent. You just tell the computer to keep brute-forcing it until something sensible emerges.
The Revolution Will Not Be TropeableThat's the point: Brute-forcing a one-time pad produces every possible message.

Da Rules excuse all the inaccuracy in the world. Listen to them, not me.I don't consider One Time Pads to be a code. It's more like steganography than actual encryption.
And yes, it is completely unbreakable, even by a magical supercomputer. Incidently, this is one of many things that seems lost on Dan Brown.

Blind Final Fantasy 6 Let's Play^ Not completely unbreakable. There's the (admittedly incredibly minuscule) chance that a random guess is a valid combination for the one time pad.
Once that happens the whole encryption scheme is compromised.
No, because even if you happen to guess the key, you have no way of knowing whether you're right. The encrypted text contains absolutely zero information about the message. It is literally impossible to break.
Blind Final Fantasy 6 Let's Playwhy so serious?
Actually, you also have to check whether the message decrypts into something sensible, otherwise it doesn't work. Also, not quite any code. Otherwise yeah, I see what you mean.
