authparser

Used to parse http Authentication headers, and to call handlers per scheme. Fully compliant with RFC7235.

How do clients authenticate with your web service? Typically, this is by way of the Authorization: header, for example:

Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiIxIiwiaWF0IjoyfQ.nMoAK-oiZTdVT0CcGhgS5yCscaNSf49BYFR3DiGT3tM

This uses the Bearer scheme, common when using OAuth (RFC6750).

What if you also want to handle Basic (RFC7617), or Digest (RFC7616)? You will need a way to parse the Authorization header and dispatch to your handler:

• process the JWT for Bearer
• base64 decode for Basic
• send the challenge response for Digest

Parsing the Authorization: header is no simple task. That's where authparser comes in.
