How to encrypt using Bacon cipher
Baconian encryption uses a substitution alphabet based on 2 letters (biliterary, usually A and B)
| A | AAAAA | B | AAAAB |
|---|---|---|---|
| C | AAABA | D | AAABB |
| E | AABAA | F | AABAB |
| G | AABBA | H | AABBB |
| I=J | ABAAA | K | ABAAB |
| L | ABABA | M | ABABB |
| N | ABBAA | O | ABBAB |
| P | ABBBA | Q | ABBBB |
| R | BAAAA | S | BAAAB |
| T | BAABA | U=V | BAABB |
| W | BABAA | X | BABAB |
| Y | BABBA | Z | BABBB |
Example: DCODE is encrypted AAABB,AAABA,ABBAB,AAABB,AABAA
In this original alphabet, the letter V does not exist, it is replaced by U, likewise the letter J does not exist, it is replaced by I.
Another bacon's alphabet is sometimes preferred, more complete, it uses a unique code for each letter:
| A | AAAAA | B | AAAAB |
|---|---|---|---|
| C | AAABA | D | AAABB |
| E | AABAA | F | AABAB |
| G | AABBA | H | AABBB |
| I | ABAAA | J | ABAAB |
| K | ABABA | L | ABABB |
| M | ABBAA | N | ABBAB |
| O | ABBBA | P | ABBBB |
| Q | BAAAA | R | BAAAB |
| S | BAABA | T | BAABB |
| U | BABAA | V | BABAB |
| W | BABBA | X | BABBB |
| Y | BBAAA | Z | BBAAB |
How to decrypt Bacon cipher
Baconian decryption is a substitution with the biliteral alphabet of Bacon.
Example: AAABB AAABA ABBAB AAABB AABAA is equivalent to DCODE.
How to recognize a Bacon ciphertext?
The ciphered message is a biliterary code (binary with 2 letters), and maybe spaces every 5 characters.
All references to Françis Bacon (and its homonyms), Novum organum, or to bacon slices (pork, larding, smocked, salted, etc.) are clues.
What are the variants of the Bacon cipher?
The letters A and B can be replaced by others characters, such as 0 and 1, to transform the message into binary format.
Sometimes the letters o and l are used: lolol loolo lolol
When Bacon cipher have been invented?
Francis Bacon first described it around 1605
