A community-maintained guide for storing GnuPG and SSH credentials on YubiKey hardware tokens, covering key creation, subkey transfer, agent configuration, and hardening. It is documentation rather than software, published as HTML and rendered on GitHub Pages.

Use cases

• set up SSH authentication with a YubiKey
• store GPG private keys on a hardware token
• create an offline certify key and subkeys
• configure gpg-agent for SSH agent forwarding
• harden a key generation environment
• rotate or renew GPG subkeys
• sign git commits and email with hardware-backed keys

When to choose

• you own a YubiKey with OpenPGP support and want hardware-backed GPG/SSH keys
• you need a step-by-step, security-hardened key setup walkthrough
• you want guidance on backups, agent forwarding, and key rotation

When to avoid

• you use a YubiKey Security Key or Bio model without OpenPGP support
• you need software or tooling rather than a written guide
• you use non-Yubico smartcards with different setup procedures
