Secure Key Manager

AES-256-GCM encrypted key storage for AI agents.

When to Use

Use this skill when:

• Storing API keys or secrets that should not be in plaintext
• Migrating from hardcoded keys in TOOLS.md to encrypted storage
• Implementing output sanitization to prevent accidental key leakage
• Rotating compromised keys in a secure vault

Do NOT use this skill if:

• You are deploying general security controls → use security-hardening
• You need to audit existing skills → use skill-security-audit
• Keys need to be shared across many team members (use enterprise vaults)
