Authorization/Authentication

Authorization and Authentication are a big deal for web development. Take OAuth, the most widely used protocol of authentication between services on the web. Such a simple idea, but with so many varying implementations (twitter, facebook, whatever...) and tricky parts in the details – it's almost impossible to get right without a library. Luckily, these crates will help you address authentication problems. For hashing and algorithm crates, see: Cryptography

Do you know something we don't?

Did we miss an important crate? Or maybe you just recently launched something that should be listed here, too? Let us know!
