SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the risk of exposing sensitive credentials to agents and subprocesses by keeping signing keys and secrets protected inside the Apple Secure Enclave and encrypted vaults.

Core Features & Use Cases

  • Secure key management: Create, list, inspect, rotate, verify, and delete hardware-bound P-256 signing keys.
  • Encrypted secret storage: Store, update, import, back up, and restore secrets so they never appear in plaintext on disk.
  • Safe command injection: Run tools with decrypted secrets injected directly into child process environments without revealing values to the agent.
  • Unattended workflows: Use time-limited sessions to let automation reuse approved secrets without repeated authentication prompts.
  • Use Case: A developer can protect API keys, private keys, and deployment credentials while still allowing build, test, and release commands to run with the right environment variables.

Quick Start

Ask the agent to use keypo-signer to create or manage Secure Enclave keys, store encrypted secrets, and run a command with approved secrets injected into the child process environment.

Frequently Asked Questions about keypo-signer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I protect API keys and secrets from being exposed to AI agents on macOS?

You can protect secrets by storing them in an encrypted vault and using Secure Enclave P-256 keys for signing. This keeps plaintext credentials off-limits to agents while allowing safe execution of child processes with injected environment variables.

Can I run unattended automation workflows with Secure Enclave keys without repeated authentication prompts?

Yes, you can use time-limited sessions to enable unattended workflows. These sessions allow automation to reuse approved secrets for automated build, test, and release commands without requiring repeated authentication prompts.

How does secure command injection work when running subprocesses with sensitive credentials?

Secure command injection works by decrypting secrets and injecting them directly into the child process environment. This allows tools to run with the necessary environment variables without ever revealing the plaintext values to the agent.

Does keypo-signer work on Intel Macs or is it limited to Apple Silicon?

keypo-signer is specifically designed for macOS Apple Silicon environments. It relies on the Apple Secure Enclave to manage hardware-bound P-256 signing keys and execute policy-aware vault and session commands safely.

What is the best way to back up and restore encrypted secrets kept in a local vault?

The best way is to use the built-in backup and restore commands provided by the keypo-signer CLI. This allows you to securely store, update, import, back up, and restore encrypted secrets so they never appear in plaintext on disk.

How do I create and manage hardware-bound P-256 signing keys for deployment credentials?

You can create, list, inspect, rotate, verify, and delete hardware-bound P-256 signing keys using the keypo-signer CLI. This manages the keys directly within the Apple Secure Enclave to ensure they remain protected.
