# Triliteral Cipher

## Triliteral Cipher Encoder

### How to encrypt using Triliteral cipher?

Triliteral cipher encryption uses a triliteral alphabet (triliteral = 3 letters, or aloso called trifid or ternary = 3 items). Each letter is then replaced by a corresponding triple of 3 letters.

Example: Encrypt DCODE with the alphabet A=AAA, B=AAB, C=AAC, D=ABA, etc. The encrypted message is: ABA AAC BBC ABA ABB

### How to decrypt Triliteral cipher?

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.

### How to decipher Triliteral without knowing the alphabet?

It is possible to transform ciphertext in mono-alphabetical substitution and use dCode solver.

### How to recognize triliteral ciphertext?

The ciphered message has 3 distinct characters equally distributed.

### What are the variants of the Triliteral cipher?

Main variants involve changing the alphabet. Another possibility is to switch to characters that are not A, B and C.

### What are the most common triliteral alphabets?

Base 3 (space ⌴ at the end = CCC):

A B C D E F G H I 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

Base 3 (space ⌴ at the beginning = AAA):

⌴ A B C D E F G H AAA AAB AAC ABA ABB ABC ACA ACB ACC BAA BAB BAC BBA BBB BBC BCA BCB BCC CAA CAB CAC CBA CBB BCB CCA CCB CCC

Frederici:

A B C D E F G H I AAB AAC ABA ABB ABC ACA ACB ACC BBA BBA BBC BAB BAA BAC BCB BCA BCC CCA CCB CAC CAA CAA CAB CBC CBA CBB

A B C D E F G H I AAC AAB ACA ACC ACB ABA ABC CAC ABB ABB CAB CAA CCA CCB CBA CBC CBB BAA CCC BAC BAB BAB BAB BCA BCC BCB

A B C D E F G H I BBA BAA BAC AAA AAC AAB ACA ACC ACB ACB ABA ABC ABB CCC CCA CCB CAA CAC CAB CBA CBC CBC CBC CBB BBB BCB

Wilkins:

A B C D E F G H I AAA AAC AAB CAA CCA CCC CBB BAA BBA BBA BBC BBB ACA ACC ACB ABA ABC ABB CBA CBC CBB CBB CAC BCA BCC BCB

### What are the 27 letters of the Triliteral Alphabet?

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

### When Triliteral have been invented ?

The first triliteral alphabet appeared between 1550 and 1650
