Updating registry `https://example.com/`

Question

As https://github.com/DaGenix/rust-crypto says, I added this to my rust-lib project:

//Cargo.toml
[dependencies]
rust-crypto = "*"

//lib.rs
extern crate "rust-crypto" as rust_crypto;

And got this:

$ cargo build --verbose
    Updating registry `https://example.com/`
Unable to update the package registry

Caused by:
  failed to fetch `https://example.com/`

Caused by:
  [16] hostname does not match certificate

There's no "example.com" neither my project, nor in his lib.

I'm not sure why you're being downvoted.

You may just have an older Cargo, when the registry was set to example.com. When did you last install it?
