Example: HALO is written
The Covenant alphabet is limited to these 26 letters, there are no numbers/digits (from 0 to 9) nor punctuation.
How to decrypt Covenant cipher?
Replace each Covenant symbol with the corresponding letter in the alphabet to form words.
Example: translates to MASTER
Words can sometimes be terms in the Covenant language of a species and therefore they will be transcribed in the English alphabet (and not translated, there is no Covenant dictionary).
How to recognize a Covenant ciphertext? (Identification)
Covenant symbols are made up of triangles, sometimes put together like a tangram or a puzzle.
All references to the Halo video game (Bungie & Microsoft) such as the spartan John-117 (Master Chief) are clues.
Although sharing the same alphabet, each species has a different lexicon. Two identical words will have two different meanings depending on the species that uses them.
