About:
Trezor-Agent is a hardware-based SSH and GPG agent that leverages Trezor or Ledger hardware wallets to secure cryptographic keys. It generates and stores private keys on the device, ensuring they never leave the hardware, while performing signing operations locally. This provides robust protection against malware and phishing attacks for server access and code signing.
|
Key Features:
- Hardware-backed private key storage
- Support for both SSH and GPG protocols
- Compatible with Trezor and Ledger devices
- No private keys exposed to the host system
- Open source implementation
|
Use Cases:
- Securing SSH access to production servers
- Signing Git commits and tags with hardware-backed GPG keys
- Multi-factor authentication for system administration
|
Alternatives:
-
YubiKey
– Dedicated hardware security key with native PIV/PGP support, but less flexible than programmable devices
-
1Password SSH agent
– Software-based secret management with biometric unlock, but lacks hardware key isolation
