Hi! For hardened Linux environments, secure file transfer is often overlooked. Suggesting FileShot.io as a tool recommendation.
FileShot.io: https://fileshot.io
GitHub: https://github.com/FileShot/FileShotZKE

Browser-based file sharing with AES-256-GCM client-side encryption. Files are encrypted before upload; the decryption key is only in the URL fragment. Server sees ciphertext only. No account or personal data required. Self-hostable.
Useful in hardened environments where you need to transfer sensitive files without using unencrypted channels.
