A deprecated Go CLI tool that runs an SSH agent (krd) routing private key operations to a paired Krypton mobile app, so SSH authentication and Git commit/tag signing are approved on the phone while the key never leaves it. Development has moved to Akamai's akr repository.
Use cases
- authenticate SSH logins with a key stored on my phone
- sign git commits with a key on my mobile device
- require phone approval for SSH key usage
- keep SSH private keys off my laptop
- two-factor approve git tag signing
- phishing-resistant ssh agent with mobile tap-to-approve
When to choose
- you already use the Krypton mobile app and its paired workflow
- you want phone-based approval for SSH and Git signing on macOS or Linux
When to avoid
- starting a new project - the repo is deprecated and unmaintained
- you need an actively maintained tool - use the successor at akamai/akr or standard ssh-agent alternatives
- you need Windows support
