+This library is an implementation of [draft-ietf-sframe-enc-03](https://datatracker.ietf.org/doc/html/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](https://github.com/goto-opensource/secure-frame-ts)
 
 ## Differences from the sframe draft
 * ratcheting is not implemented
 * keyIds are used as senderIds
-* no metadata authentication 
+* no metadata authentication
 
 ## Supported crypto libraries
 Currently two crypto libraries are supported:
-- [ring](https://crates.io/crates/ring) 
+- [ring](https://crates.io/crates/ring)
     - is enabled per default with the feature `ring`
     - supports compilation to Wasm32
     - Aes-CTR mode ciphers are not supported
 - [openssl](https://crates.io/crates/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](https://docs.rs/openssl/0.10.55/openssl/).

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