truffleHog is a Python-based tool to search Git for high entropy strings, digging deep into commit history and branches. This is effective at finding secrets accidentally committed.
truffleHog previously functioned by running entropy checks on git diffs. This functionality still exists, but high signal regex checks have been added, and the ability to surpress entropy checking has also been added.

truffleHog will go through the entire commit history of each branch, and check each diff from each commit, and check for secrets. This is both by regex and by entropy. For entropy checks, it will evaluate the shannon entropy for both the base64 charset and hexidecimal charset for every blob of text greater than 20 characters comprised of those character sets in each diff. If at any point a high entropy string >20 characters is detected, it will print to the screen.
