Section 4 — The Pad
Key as long as the message, truly random, used exactly once: provably secure and almost impossible to run at scale.
| Entry | Section | What it promised, and what broke it |
|---|---|---|
| One alphabet for another | Substitution | The oldest idea in the subject, and the one that letter frequency dismantles in an afternoon. |
| The table that held for three centuries | Polyalphabetic | A grid of shifted alphabets with a repeating keyword defeated frequency analysis and was called indecipherable for three hundred years — until someone noticed that the keyword repeats, and that the repetition shows. |
| Wiring it into metal | Machines | Rotors turn the substitution at every keystroke, so the alphabet never repeats within any practical message. |
| Unbreakable, and almost unusable | The Pad | Key as long as the message, truly random, used exactly once: provably secure and almost impossible to run at scale. |
| Procedure, not mathematics | Broken | Almost every historical break came from how a system was used rather than from the system itself. |
| Read for years | Broken | Systems broken quietly and left in service, because the break was worth more than the warning. |
Each entry states the promise the system made and the specific thing that broke it — usually procedure rather than mathematics.
