SecureShell Go

SecureShell Go is a fast, security-first SSH terminal and SFTP client for
Linux servers. Run a real interactive xterm-256color shell and transfer
files over SFTP, with trust-on-first-use host-key verification at the
core.

A changed host key blocks the connection outright, with SHA256
fingerprints shown for out-of-band verification and an explicit,
checkbox-gated override required to proceed. Passwords, private keys, and
passphrases are kept only in encrypted secure storage.

Includes a saved host manager, password and private-key authentication,
and an SFTP file browser for uploads, downloads, and whole-folder
transfers, alongside the terminal in the same session.
