Keychain Manager

Security is convenience. If it's hard to use secure keys, people revert to passwords. Netcatty's Keychain is a centralized, encrypted, and portable management system for your SSH keys and Identities.

Security Architecture

Netcatty prioritizes clear separation between local convenience and cloud security.

• Local Persistence: All your Vault data (Hosts, Keys, Identities) is stored locally in your operating system's standard application data directory.
• Encrypted Sync: For advanced security during synchronization, Netcatty implements Zero-Knowledge Cloud Sync, which encrypts your data locally before it ever leaves your machine.
• Result: Your secrets remain under your control, whether stored locally or synced across devices.

Importing Existing Keys

You already have keys in ~/.ssh/. Netcatty makes it easy to adopt them.

1. Drag and Drop: Drag your private key file directly into the Keychain window.
2. Paste Content: Manually paste PEM (OpenSSH) or PKCS#8 formatted keys.
3. Key Generation: Create new keys directly within the app using the built-in generator.

Identities (The "User Profile")

A raw key (id_ed25519) is useless without a username. An Identity binds them together: root + My Production Key.

• Why? You might use the same key for ubuntu on AWS and root on DigitalOcean.
• Workflow: Creates the Identity once. Assign it to 50 hosts. Rotate the key in one place, and all 50 hosts update instantly.
