Baconian Cipher Encoder/Decoder Baconian Cipher Encoder/Decoder (BAC) Turn text into Bacon’s 5-letter A/B code or decode existing A/B groups back to normal letters. Supports classic 24-letter Bacon, 26-letter extension, and custom symbols like 0/1 or X/Y. You can even map it onto a “cover text” using uppercase/lowercase steganography. Encode (text ➜ A/B) Decode (A/B ➜ text) Alphabet variant Original 24-letter (I=J, U=V) Modern 26-letter (all letters) Choose the same variant your source used. Symbol for “A” Symbol for “B” Group in 5s Keep non-alphabet chars Input text Francis Bacon Output Convert Clear Optional: hide A/B in a cover text Paste a cover text. We will replace characters with uppercase (=A) and lowercase (=B) according to your encoded sequence. Extra cover characters will stay the same. Cover text Stego output (A=UPPER, B=lower) Build stego text How the Baconian cipher works The cipher turns every letter into a block of 5 characters, each either “A” or “B”. For example, in the original 24-letter alphabet: A = AAAAA B = AAAAB C = AAABA ... I/J = ABAAA U/V = BAABB Once you have the A/B sequence, you can hide it in many ways: two fonts, two typefaces, two colors, or simply upper/lowercase. A recipient who knows the scheme can map it back to As and Bs and then to letters. 24 vs 26 letters 24-letter (classic): I=J and U=V are merged to fit 24 patterns. 26-letter (extended): every letter A–Z is unique. Pick this if you don’t want merged letters. Common decoding problems Make sure the symbol you use for A and B is the same throughout. If the encoded message length is not a multiple of 5, the last letter may be incomplete. If the original text used the 24-letter alphabet, decoding with 26-letter mode will produce odd results.
