FAQ
What's the standard English letter frequency?+
E (12.7%), T (9.0%), A (8.2%), O (7.5%), I (7.0%), N (6.7%), S (6.3%), H (6.1%), R (6.0%). Other letters drop off from there.
Why does this matter for cryptography?+
Substitution ciphers preserve letter frequency. If your ciphertext has 13% Q, Q is probably E. This is how you crack a Caesar cipher in your head.
