This Android app stores your SSH key phrase and sends it to your PC securely via the LAN when an authorized fingerprint is detected by the Android fingerprint scanner.
*The PC must run Linux and have FiSSH desktop installed - see [https://git.iodev.science/ioan/FiSSH-Desktop/src/branch/master/INSTALL.md INSTALL.md here]
*The PC app then returns the received passphrase to OpenSSH and the standard ssh binary completes the login process.
*It is important to note that none of the FiSSH apps have access to private key file and that FiSSH uses TLS sockets with certificate validation to prevent man-in-the-middle attacks!
