WebRTC 0.11 triggers a panic with "no process-level CryptoProvider available -- call CryptoProvider::install_default() before this point" #567

Closed paultag closed 4 months ago

paultag commented 4 months ago

WebRTC 0.10 works fine -- but when I've upgraded to 0.11, there's a crash due to the changed with the rusttls backend.

We worked around this by installing our own crypto backend; but I didn't see anything in the Examples about this, so I figured I'd open an issue that can be closed as "works as intended" if this is part of the new API

(for those at home, something like)

rustls::crypto::ring::default_provider().install_default().unwrap()
Backtrace Specifically, from a spawned task, the WebRTC negotiation code crashes with `no process-level CryptoProvider available -- call CryptoProvider::install_default() before this point`. This happens right after the rtc ice connection state changed to connected, so perhaps part of the changed DTLS codepath. ``` thread 'tokio-runtime-worker' panicked at /home/paultag/.cargo/registry/src/index.crates.io-6f17d22bba15001f/rustls-0.23.5/src/crypto/mod.rs:260:14: no process-level CryptoProvider available -- call CryptoProvider::install_default() before this point stack backtrace: 0: 0x559b6886321c -
