Are you ready to get freaky?

This library provides a way to train a model that predicts the "randomness" of an input ByteString.

freq

About

This is a simple cryptanalytic frequency analysis tool that uses english character digrams as a probabilistic model for scoring ByteStrings according to their randomness (0..1, 0 being the most random, 1 being the least random).

Uses

I currently use this to validate domain names, and so the training data available consists of about 6.5 Megabytes of Public Domain 19th and 20th century English novels. You can feed any training data you wish to 'freq' to achieve different results.
