System.Net.Security is not supported on os-wasi #94980

Open richlander opened 10 months ago

richlander commented 10 months ago

I was trying to use HttpClient with an https endpoint with wasi, with a program similar to one at SteveSandersonMS/spiderlightning-dotnet (with the addition of HttpClient usage).

We should resolve this or provide guidance in the message on the alternative. HTTPS is pretty common.

Ideally, HttpClient uses a Wasi HttpHandler implementation by default that supports SSL/TLS and if scenarios require it, we have an option to bundle OpenSSL and ca-certificates. We've had a longstanding policy not to ship OpenSSL, however, we ship it with our containers and wasm seems very similar to that.

Unhandled Exception:
System.PlatformNotSupportedException: System.Net.Security is not supported on this platform.

The long term plan here would be to implement a platform abstraction for System.Net.Security that wrapped https://github.com/WebAssembly/wasi-crypto in its final form. There are also other options available for technology demonstrations/non-shipping code.
