Advanced Bacon's Cipher

Use direct Bacon symbols, custom A/B pairs, 24/26-letter alphabets, and hidden case-based steganography.

Encoding system

Bacon maps each plaintext letter to a five-symbol binary pattern. The symbols do not have to be literal A and B; any distinct pair such as 0 / 1, X / Y, or . / - works.

Hidden mode embeds Bacon using two visible text states: lowercase letters represent A and uppercase letters represent B. The first 16 cover letters store the payload length.

Using This Tool: Guide & Notes Show guide

Advanced Bacon supports direct A/B symbols, custom symbol pairs, alphabet variants, and case-based steganography.

How to use it

Choose the representation mode you want to use.
Select the alphabet variant and symbol settings.
Enter the visible message or Bacon pattern.
Check the preview to confirm the hidden or direct output is preserved.

Options and settings

Direct mode writes the A/B pattern plainly.
Custom symbols replace A and B with your chosen pair of markers.
Case-based mode hides the pattern in uppercase and lowercase styling.
Alphabet variant controls 24-letter historical handling versus modern 26-letter handling.

Notes

Case-based hiding can be destroyed by systems that normalise text case.
The visible carrier text must be long enough to hold the hidden Bacon pattern.
