portal-client

This crate contains the client-side application for Portal - An encrypted file transfer utility.

• Negoticate a symmetric key with a peer using SPAKE2
• Encrypt files with Chacha20poly1305 using the RustCrypto implementation
• Send/receive files through a Portal relay

Note: The peer must connect to the same portal-relay as you. The default relay is portal-relay.landhb.dev but can be changed in your config. On linux the config is most commonly located at ~/.config/portal/portal.toml.
