SFTP and TLS Transfer Suite

SFTP and TLS Transfer Suite is an independent open-source Linux dual-pane
secure file transfer workbench powered by bundled OpenSSH (sftp, scp, ssh,
ssh-keygen, ssh-keyscan) and Python TLS (ftplib.FTP_TLS).

Key Features:
- Dual Local <-> Remote Session Commander (Tab 0): Multi-session tabs with
Quick Connect for OpenSSH SFTP, SCP, Explicit FTPS (AUTH TLS + PROT P),
Implicit FTPS, and FTP. Includes dual directory panes, Upload, Download,
MkDir, Rename, Chmod, Delete, a SHA-256 verified Transfer Queue with
resumable transfers, and a live protocol console.
- Synchronize Preview & Resumable Mirror (Tab 1): Compare local and remote
directory trees in Dry-Run mode (Upload Newer, Download Missing, Mirror)
before executing resumable transfers with SHA-256 verification logging.
- PBKDF2 Site Manager & Ed25519 Key Vault (Tab 2): Store encrypted site
profiles using PBKDF2-HMAC-SHA256 (200,000 rounds) plus HMAC-authenticated
encryption, generate Ed25519 or RSA-4096 key pairs via bundled ssh-keygen,
and manage host keys via ssh-keyscan strictly inside the isolated snap
user common directory without requesting host ssh-keys access.
- Bilingual English and Vietnamese UI with instant runtime switching.
