# Class Nethttp_client.digest_auth_handler

    class digest_auth_handler : #key_handler -> auth_handler

Digest authentication. Authentication information is obtained by the passed key_handler.

This handler is compatible with RFCs 2069, 2617 and 7616. In particular, the following protocol options are available:

- The algorithms MD5, MD5-sess, SHA256 and SHA256-sess are implemented
- The quality of protection mode "auth" is implemented. The optional mode "auth-int" has been omitted.
- The information of the `Authentication-Info` header is completely ignored

This handler is implemented on top of `Netmech_digest_http.Digest`.
