Simple Bacon's Cipher

Encode letters as five-character A/B groups using the classical 24-letter Bacon alphabet.

Encoding system

This simple version uses the classical 24-letter Bacon alphabet. J is treated as I, and V is treated as U.

Alphabet: 24 letters Symbols: A / B Letter width: 5 A: AAAAA Z: BABBB

Options

Keep punctuation & numbers

Remove spaces between A/B groups

Uppercase plaintext output

Group A/B stream

Encrypt mode converts each letter into a five-character A/B group. Decrypt mode reads A/B groups back into letters.

Output stats

Mode: Encrypt Letters processed: 0 A/B groups: 0 Input chars: 0 Output chars: 0 Ignored A/B chars: 0

Example: plaintext HELLO WORLD becomes AABBB AABAA ABABA ABABA ABBAB BABAA ABBAB BAAAA ABABA AAABB. This is the simple educational version; the more advanced Bacon tool can later add disguising and richer variants.

Using This Tool: Guide & Notes Show guide

Simple Bacon turns letters into five-symbol A/B groups using Baconian alphabet patterns.

How to use it

Choose Encode to turn letters into Bacon groups, or Decode to reverse them.
Paste text or A/B groups into the input box.
Check that groups are complete before decoding.
Use grouping options to keep the output readable.

Options and settings

Alphabet variant controls whether the historical 24-letter or modern 26-letter style is used.
Group size changes how encoded groups are visually separated.
Unsupported-character handling decides whether spaces and punctuation are kept or ignored.
Case options affect display, not the underlying A/B pattern.

Notes

Historical Bacon often combines I/J and U/V.
Bacon can be used as a visible encoding or as a steganographic pattern.

A note from the team

We build these tools because we love cryptography, encoding, and making difficult ideas easier to explore. If they've helped you, even a small coffee means the world to the project. Thank you!
