What is secure digest authentication?
Digest Access Authentication is a way for service providers to verify a person’s credentials by using a web browser. Specifically, digest access authentication uses the HTTP protocol, applying MD5 cryptographic hashing and a nonce value to prevent replay attacks.
What is a password digest?
Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user’s web browser. Technically, digest authentication is an application of MD5 cryptographic hashing with usage of nonce values to prevent replay attacks.
How does Digest Authentication work?
Digest authentication is a method of authentication in which a request from a potential user is received by a network server and then sent to a domain controller. The domain controller sends a special key, called a digest session key, to the server that received the original request.
How is the HTTP digest authentication scheme used?
HTTP provides a simple challenge-response authentication mechanism that may be used by a server to challenge a client request and by a client to provide authentication information. This document defines the HTTP Digest Authentication scheme that can be used with the HTTP authentication mechanism.
What’s the difference between basic and digest access authentication?
This document also provides the specification for HTTP’s authentication framework, the original Basic authentication scheme and a scheme based on cryptographic hashes, referred to as “Digest Access Authentication”. It is therefore also intended to serve as a replacement for RFC 2069 [6].
Do you have to reset passwords with digest authentication?
You will have to ensure that all users reset their passwords. Digest authentication does the same thing as Basic authentication, but it provides a security improvement in the way in which a user’s credentials are sent across the network.
Which is digest authentication protocol does Microsoft use?
Microsoft provides digest authentication as a means of authenticating Web applications that are running on IIS. Digest authentication uses the Digest Access Protocol, which is a simple challenge-response mechanism for applications that are using HTTP or Simple Authentication Security Layer (SASL) based communications.
