Crate portal_lib

A small Protocol Library for Portal - An encrypted file transfer utility

This crate enables a consumer to:

• Create/serialize/deserialize Portal request/response messages.
• Negoticate a symmetric key with a peer using SPAKE2
• Encrypt files with Chacha20-Poly1305 using either the RustCrypto implementation or Ring’s
• Send/receive files through a Portal relay

The library is broken up into two abstractions:

• A higher level API, exposted via the Portal struct, to facilitate automating transfers easily
• A lower level API, exposed via the protocol::Protocol struct, if you need access to lower-level facilities

Re-exports
