About:
Squealer is a secret scanning tool that analyzes Git repositories and filesystems to detect sensitive information exposed in commit histories. It identifies hardcoded credentials, API keys, and other secrets that developers may have accidentally committed over time. The tool helps organizations proactively identify and remediate security vulnerabilities before they can be exploited.
Key Features:
  • Scans Git commit history for secrets and credentials
  • Supports multiple secret detection patterns and rules
  • Provides detailed output with file paths and commit hashes
  • Can scan local filesystems in addition to Git repositories
  • Configurable severity levels and rule sets
Use Cases:
  • Auditing legacy repositories for accidentally committed secrets
  • Pre-deployment security scanning in CI/CD pipelines
  • Incident response when investigating potential credential leaks
  • Compliance auditing for security best practices
Alternatives:
  • gitleaks – More widely adopted with extensive rule library; Squealer offers simpler configuration
  • truffleHog – Similar functionality with entropy-based detection; Squealer focuses on pattern matching
  • git-secrets – AWS-maintained tool focused on pre-commit hooks; Squealer provides broader scanning capabilities
