How to use Bacon Cipher

Bacon's cipher, or biliteral cipher, encodes each letter of the message over five symbols taking only two values (A/B, or 0/1). Devised by Francis Bacon in the 16th century, it could hide a message in the typography of a cover text (two typefaces = A and B), which also makes it a steganography tool. Choose the classic 24-letter variant (where I=J and U=V) or the modern 26 distinct letters, then encrypt or decrypt. Processing is entirely local

Frequently asked questions

What's the difference between the 24 and 26 letter variants?

The original merges I with J and U with V (24 codes). The 26-letter variant gives each letter a distinct code, removing decryption ambiguity

Why is it called steganography?

The two symbols A and B can be hidden in an innocuous text via case, font or formatting, concealing the very existence of the message
