**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

**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.

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

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
