no process-level CryptoProvider available -- call CryptoProvider::install_default() before this point

[t348575]

After upgrading tokio-tungstenite to 0.23 from 0.22, I get the below panic when connecting to a secured websocket endpoint.

My Cargo.toml entry: tokio-tungstenite = { version = "0.23", features = ["rustls-tls-webpki-roots"] }

this might have something to do with it?

The panic:

[cernicc]

It might also be this?

[t348575]

Yep, missed that.

[Zercerium]

Hi, will this change be reverted? currently I have to add rustls by myself as a dependency and enable the aws_lc_rs feature if I want to use rustls with this create.

[agalakhov]

You can always call CryptoProvider::install_default() manually. It should be done once at the very beginning.

[Zercerium]

thanks a lot for the reply. For clarification, in this case I would also have to include rustls to call CryptoProvider::install_default() cause it is not exported by tokio_tungstenite and I have to provide my own CryptoProvider cause CryptoProvider::install_default() needs a self reference.

[jiangxiaoqiang]

add this to fixed this issue:

rustls::crypto::ring::default_provider().install_default().expect("Failed to install rustls crypto provider");
