Monoalphabetic Cipher
Monoalphabetic ciphers leak information. Can you recover it?
A monoalphabetic cipher is one in which characters of an alphabet are mapped to a permutation of the alphabet. This text was encrypted with a monoalphabetic cipher using a random permutation of the alphabet as the key. The alphabet used is only upper case letters, no spaces or punctuation.
Find the md5 hash of the plain text. Submit the solution in lower case hex.
