# Cryptographic Key Material Exposure

## Overview
Private keys and key material committed to version control or hardcoded in source permanently compromise:
- TLS certificates (can intercept all encrypted traffic)
- SSH keys (unauthorized server access)
- JWT signing keys (forge authentication tokens)
- PGP keys (decrypt private communications)

## Remediation
- Use `.gitignore` to exclude all key files
- Rotate any exposed keys immediately — treat them as compromised
- Use secrets management systems (Vault, AWS Secrets Manager)
- Use hardware security modules (HSM) for production key storage
