Research direction

Start by tracing rustup's OpenSSL API usage and reviewing how the OpenSSL build features are configured. Identify the algorithms and features actually used, then verify that the build applies only that minimal set and preserves rustup's existing HTTPS behavior.

Description

enhancement
Problem you are trying to solve

We shouldn't build a full feature/algo set with ssl libraries, as we're just using a limited set of algo and features of openssl.
So maybe we can trace down to the minimal used set of openssl.

This would have these benefits:

  1. Better binary size
  2. Less build time
  3. More control over the build system, making sure that issues like https://github.com/rust-lang/rustup/issues/4979 happen less.
Solution you'd like

Trace the API usage of openssl, finding the minimal features that rustup is using, then we apply the minimal feature set to openssl build, making this possible.
