A triliteral cipher is, as its name suggests, a cipher that uses 3 letters (it is also called ternary, or trifid, for 3 elements).
It is a cipher by substitution, a plain letter being replaced by a triplet of 3 letters.
The Triliteral cipher uses a substitution triliteral alphabet (which can be defined more or less randomly).
Example: Encrypt DCODE with the alphabet A=AAA, B=AAB, C=AAC, D=ABA, etc. The encrypted message is: ABA AAC BBC ABA ABB
Base 3 (space ⌴ at the end = CCC):
A | AAA | B | AAB | C | AAC | D | ABA | E | ABB | F | ABC | G | ACA | H | ACB | I | ACC |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
J | BAA | K | BAB | L | BAC | M | BBA | N | BBB | O | BBC | P | BCA | Q | BCB | R | BCC |
S | CAA | T | CAB | U | CAC | V | CBA | W | CBB | X | CBC | Y | CCA | Z | CCB | ⌴ | CCC |

Triliteral Decryption requires to know the trileteral alphabet used in order to perform a substitution.
Example: The ciphered message ABAAACBBCABAABB have been encoded with the alphabet A=AAA, B=AAB, C=AAC, D=ABA, etc. The original plain text is DCODE.
It is possible to transform ciphertext in mono-alphabetical substitution and use dCode solver.
The ciphered message has 3 distinct characters equally distributed. It is usually the 3 letters A, B and C but it can be 3 numbers, or 3 different things.
Like a Bacon cipher, it is possible to hide a Triliteral cipher in a text, for example by alternating 3 fonts, or variations of letters: uppercase, lowercase, bold, italic, underlined, etc.
All notions of triplet, number 3, triple, words trifid, triliteral, tricode, triletter, tridigital, etc. are clues.
The list of permutations with repetition of 3 characters A, B and C is: AAA, AAB, AAC, ABA, ABB, ABC, ACA, ACB, ACC, BAA, BAB, BAC, BBA, BBB, BBC, BCA, BCB, BCC, CAA, CAB, CAC, CBA, CBB, CBC, CCA, CCB, CCC
The first triliteral alphabet appeared between 1550 and 1650.
