About:
KeepkeyAgent is a hardware-based SSH and GPG agent that leverages a Keepkey hardware wallet for secure key storage and cryptographic operations. It ensures that private keys for SSH authentication and GPG signing never leave the secure hardware device, providing robust protection against malware and key exfiltration. This tool integrates with standard agent protocols to offer a seamless yet highly secure developer workflow.
Key Features:
  • Hardware-based private key storage
  • Secure SSH authentication and GPG signing
  • Protection against private key extraction
  • Integration with standard OpenSSH and GPG tools
Use Cases:
  • Securing SSH access to production servers
  • Signing Git commits with hardware-backed GPG keys
  • Managing cryptographic keys for developers in high-security environments
Alternatives:
  • YubiKey – YubiKey is a widely supported hardware token for 2FA and PGP, whereas KeepkeyAgent specifically utilizes the Keepkey device for SSH/GPG agent functionality.
  • 1Password SSH – 1Password offers integrated software-based SSH key management, while KeepkeyAgent relies on external hardware for an air-gapped security model.
