Tool to analyze trigrams appearance frequency in a message. A trigram is the association of 3 characters, usually 3 letters that appear consecutively in a message.
Trigrams (groups of three 3 letters) are used in some encryptions in cryptography. There are 2 main modes of appearance of trigrams:
- A trigram can appear when a single character (or a bigram) is encrypted by 3 characters.
Example: A can become 'BCD', or AB can become CDE
- A trigram can be derived from the encryption of another trigram
Example: ABC can become DEF
