# @suaveplan/security-codes - Detect and sanitise sensitive security-code leakage in strings: API keys, JWTs, credit cards, GitHub tokens, Stripe keys, SSH keys, PEM blocks, AWS access keys, and more
## Summary
Detect and sanitise sensitive security-code leakage in strings. Handles API
keys, JWTs, credit cards, GitHub tokens, Stripe keys, SSH keys, PEM blocks,
AWS access keys, OpenAI keys, Google API keys, and high-entropy heuristics.

## Features
- **10 built-in pattern detectors** covering the most common secret types
- **Pluggable detector API** — register custom patterns at runtime
- **4 masking strategies** — full-redact, partial, hash, tokenize
- **Overlap deduplication** — higher-confidence matches win
- **OTel metrics** — `security_codes.detect.total` and `security_codes.detect.duration_ms`
- __Zero @suaveplan/_ runtime dependencies_* — leaf package, no circular risk
## Install
```bash
bun add @suaveplan/security-codes
```
## Quick Start
```ts
import { SecurityCodeDetector, SecurityCodeSanitizer } from '@suaveplan/security-codes';
const detector = new SecurityCodeDetector();
const matches = detector.detect('aws_key=AKIAIOSFODNN7EXAMPLE');
const sanitizer = new SecurityCodeSanitizer();
const { output } = sanitizer.sanitize('aws_key=AKIAIOSFODNN7EXAMPLE');
// output === 'aws_key=[REDACTED]'
```
