Keyward is a keyboard-driven terminal UI that centralizes SSH key
management, config editing, and security auditing in a single interface.

It discovers and displays all SSH keys with their types, sizes, and
fingerprints, and produces an A-F graded security audit that flags weak
keys, missing passphrases, and risky configuration settings.  Hosts in
~/.ssh/config can be edited with validation and automatic backups, and
metadata and full backup archives are encrypted with age.

Keyward is a single static binary with no daemon and works offline.
