yb

Command-line tool for storing encrypted binary blobs on a YubiKey using the PIV application. Blobs are encrypted with ECDH (the private key never leaves the YubiKey) and AES-256-GCM, and signed. Includes a guided setup (yb format), a health report of the YubiKey and the store (yb fsck), management key rotation, glob-pattern blob selection, and shell completions for bash, zsh, and fish.
