Secure Frame (SFrame)

This library is now continued and maintainend under https://github.com/TobTheRock/sframe-rs

This library is an implementation of draft-ietf-sframe-enc-03 and provides and end-to-end encryption mechanism for media frames that is suited for WebRTC conferences. It is in it's current form a subset of the specification. There is an alternative implementation under goto-opensource/secure-frame-ts

Differences from the sframe draft

• ratcheting is not implemented
• keyIds are used as senderIds
• no metadata authentication

Supported crypto libraries

Currently two crypto libraries are supported:

• ring
  • is enabled per default with the feature ring
  • supports compilation to Wasm32
  • Aes-CTR mode ciphers are not supported
• openssl
  • is enabled with the feature openssl
    • To build e.g. use cargo build --features openssl --no-default-features
  • uses rust bindings to OpenSSL.
  • Per default the OpenSSL library is locally compiled and then statically linked. The build process requires a C compiler, perl (and perl-core), and make. For further options see the openssl crate documentation.
  • Compilation to Wasm32 is not yet supported

Both cannot be enabled at the same time, thus on conflict sframe issues a compiler error.
