Where is the cargo certificate bundle


Anyone know where cargo on Windows (or curl specifically, cargo uses curl right?) looks for the ssl certificate bundle? I’m having trouble related to https://github.com/rust-lang/cargo/pull/2408 (behind a proxy that decrypts ssl connections.) However, I do have admin access to my machine, and did install the appropriate certificates. I still get this error though:

> cargo build --verbose
