Ciphertext:
In a monoalphabetic subsitution cipher, every letter is replaced by a different letter. There are roughly 26! or 403,291,461,126,605,635,584,000,000 different keys, which would apparently make it impossible to check every key. But by looking at the frequencies of letters and letter combinations, it's actually pretty easy to crack most substitution ciphers.
