GitHub - http-auth/http-auth: Node.js package for HTTP Configurations. realm - Authentication realm, by default it is Users.; file - File where user details are stored.. Line format is {user:pass} or {user:passHash} for basic access.; Line format is {user:realm:passHash} for digest access.; algorithm - Algorithm that will be used only for digest access authentication.. MD5 by default.; MD5-sess can be set.; qop - Quality of protection that is used Digest Authentication - World Wide Web Consortium Digest Authentication Current proposal: draft-ietf-http-digest-aa-02.txt Adding an algorithm parameter. Describe in detail construction of nonces. Here there are a number of tricks already in use which ensure that a nonce is only valid for requests comming from a single TCP/IP address.

If no authentication method is given with the auth argument, Requests will attempt to get the authentication credentials for the URL's hostname from the user's netrc file. The netrc file overrides raw HTTP authentication headers set with headers=. If credentials for the hostname are found, the request is sent with HTTP Basic Auth. HTTP authentication uses methodologies via which web servers and browsers securely exchanges the credentials like usernames and passwords. HTTP authentication or we can also call it as Digest Authentication follows the predefined methods/standards which use encoding techniques and MD5 cryptographic hashing over HTTP protocol. Digest Access Authentication is one method that a client and server can use to exchange credentials over HTTP. This method uses a combination of the password and other bits of information to
Digest does provide better in-transit security than Basic authentication for unencrypted traffic, but it's weak. It is MUCH safer to use Basic auth in combination with SSL/TLS instead, because that way you can also keep the passwords on the server encrypted. – rustyx Jul 9 '16 at 14:24
Digest authentication is defined in RFC 2617 so please refer to this documentation instead of coming up with your own scheme. It may also be vulnerable to replay attacks The nonce set by the server is used to defend against replay attacks, i.e. only replies are accepted which match the unpredictable nonce.
