In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name and password when making a request. In basic HTTP authentication, a request contains a header field in the form of Authorization: Basic <credentials> , where <credentials> is the Base64 encoding of ID ...
RoadRunner is an open-source application server, load-balancer and process manager written in Go and implemented by PHP 7. It is used in rapid application development to speed up the performance of large web applications for users.
The authentication process in this protocol is always initiated by the server/host and can be performed anytime during the session, even repeatedly. The server sends a random string (usually 128B long). The client uses the password and the string received as input to a hash function and then sends the result together with username in plain text.
For a typical web application, the application server sits behind the web servers. An application server framework is a service layer model. It includes software components available to a software developer through an application programming interface. An application server may have features such as clustering, fail-over, and load-balancing.
Simple Authentication and Security Layer (SASL) is a framework for authentication and data security in Internet protocols. It decouples authentication mechanisms from application protocols , in theory allowing any authentication mechanism supported by SASL to be used in any application protocol that uses SASL.
Authentication is used as the basis for authorization, which is the determination whether a privilege may be granted to a particular user or process, privacy, which keeps information from becoming known to non-participants, and non-repudiation, which is the inability to deny having done something that was authorized to be done based on the ...
PAP authentication is only done at the time of the initial link establishment, and verifies the identity of the client using a two-way handshake. Client sends username and password. This is sent repeatedly until a response is received from the server. Server sends authentication-ack (if credentials are OK) or authentication-nak (otherwise) [2]
