Master the Ciphers
01. ARISTOCRAT
The classic monoalphabetic substitution cipher. Each letter in the message is replaced by another unique letter of the alphabet. Original word spacing and punctuation are preserved, providing key contextual clues.
02. PATRISTOCRAT
A more advanced variation of the Aristocrat. While it still uses monoalphabetic substitution, all spaces and punctuation are completely removed, and the ciphertext is grouped into uniform 5-letter blocks.
03. ATBASH
A simple yet elegant substitution cipher where the alphabet is perfectly reversed. 'A' becomes 'Z', 'B' becomes 'Y', and so on.
04. CAESAR
Named after Julius Caesar, this cipher shifts every letter in the plaintext by a fixed number of positions down the alphabet. Identify the shift value to unlock the message.
05. PORTA
A sophisticated polyalphabetic substitution cipher from the 16th century. It uses a secret keyword to rotate substitutions based on a reference tableau.
06. BACONIAN
A unique steganographic cipher created by Francis Bacon. Each letter of the plaintext is represented by a specific 5-character sequence composed only of 'A' and 'B'.
