Key Auth

KeyAuth protects routes with an API key validator.

app.Use(middleware.KeyAuth(middleware.KeyAuthStatic(os.Getenv("API_KEY"))))

By default, Zinc reads Authorization: Bearer <key>.

Use another extractor when keys live somewhere else.

app.Use(middleware.KeyAuthWithConfig(middleware.KeyAuthConfig{
  Extractor: middleware.KeyAuthFromHeader("X-API-Key"),
  Validator: middleware.KeyAuthStatic("secret"),
}))

Available extractors:

• KeyAuthFromAuthorizationHeader()
• KeyAuthFromHeader(header)
• KeyAuthFromHeaderPrefix(header, prefix)
• KeyAuthFromQuery(name)
• KeyAuthFromCookie(name)
• KeyAuthFromFirst(...)

Inside handlers, use KeyAuthCurrent(c) or MustKeyAuthCurrent(c) to read the accepted key source.
