Smart Secrets Scanner

smart-secrets-scanner

Intelligent secrets detection — scan code, configs, and git history for exposed API keys, passwords, tokens, and credentials before they leak.

Skill Metadata

• Slug: smart-secrets-scanner
• Version: 1.0.0
• Description: Intelligent secrets and credential scanner for codebases. Detects exposed API keys, passwords, tokens, private keys, and credentials in source code, config files, environment variables, and git commit history. Provides auto-remediation suggestions.
• Category: security
• Trigger Keywords: secrets scanner, credential leak, API key detection, token exposure, security scan, secret detection, git secret

Capabilities

1. Scan Current Project

```bash node scanner.js scan ./src node scanner.js scan ./ --include ".js,.json,.yaml,.env*" ``` Detects 50+ patterns: AWS keys, GitHub tokens, Slack webhooks, database URLs, private keys, JWTs, etc.

2. Scan Git History

```bash node scanner.js git-scan --depth 50 node scanner.js git-scan --since "2024-01-01" ``` Finds secrets that were committed and later removed (still in git history).

3. Pre-commit Hook

```bash node scanner.js hook --install

Now every commit is scanned automatically

```

4. Auto-Redact

```bash node scanner.js redact ./src/config.js --replace-with "[REDACTED]" ``` Replace detected secrets with placeholder values.

Detection Patterns

Use Cases

1. CI/CD Pipeline: Block deployments with exposed secrets
2. Pre-commit: Prevent secrets from entering git history
3. Audit: Scan existing codebase for leaked credentials
4. Compliance: SOC2, GDPR requirement for credential management
5. Education: Teach developers about secret management

Output Format
