TruffleHog is a high-accuracy secret-detection tool designed to uncover exposed credentials such as API keys, tokens, private keys, and cloud secrets across large codebases. Originally created to scan Git commit history, it has evolved into a multi-source scanning engine capable of analyzing GitHub, GitLab, Bitbucket, Docker images, file systems, Terraform states, and cloud environments.

The scanner combines entropy detection, an extensive library of regular expression detectors, and live credential validation to minimize false positives. TruffleHog is widely used in security research, supply chain security, DevSecOps workflows, and bug bounty programs. Its speed, accuracy, and broad ecosystem coverage make it a core tool for identifying and preventing credential leakage in modern software development.
