Support custom crypto backends via rustls-no-provider #7059
Description
I'd like to integrate and test rustpython in another project utilizing https://github.com/ctz/graviola and rustls instead of aws-lc-rs. However currently rustpython hard codes aws-lc-rs in the Cargo.toml. Is this something that could be supported?
reqwest has a rustls-no-provider option where you are able to use graviola like this:
fn main() {
rustls_graviola::default_provider().install_default().unwrap();
// ... rest of main function
}However I see that there are a few mentions of aws_lc_rs imports directly in the rustpython stdlib 🤔
See
RustPython/crates/stdlib/Cargo.toml

Hi! There is no specific reason to stick on aws_lc_rs. That was selected as default because it is the recommendation of rustls team.
Could you help us to patch ssl.rs not to use aws_lc_rs directly?
