To use PHP with an HTML form, the URL of the PHP script is specified in the action attribute of the form tag. The target PHP file then accesses the data passed by the form through PHP's $_POST or $_GET variables, depending on the value of the method attribute used in the form. Here is a basic form handler PHP script that will display the ...
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.This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history.
Laminas Project (formerly Zend Framework or ZF) is an open source, object-oriented web application framework implemented in PHP 7 and licensed under the New BSD License. [3] The framework is basically a collection of professional PHP [4]-based packages. [5]
Because many users re-use passwords for multiple sites, the use of a salt is an important component of overall web application security. [14] Some additional references for using a salt to secure password hashes in specific languages or libraries (PHP, the .NET libraries, etc.) can be found in the external links section below.
Login modules are written by implementing this interface; they contain the actual code for authentication. It can use various mechanisms to authenticate user credentials. The code could retrieve a password from a database and compare it to the password supplied to the module.
In computer programming, create, read, update, and delete (CRUD) are the four basic operations (actions) of persistent storage. [1] CRUD is also sometimes used to describe user interface conventions that facilitate viewing, searching, and changing information using computer-based forms and reports.
Benefits of using single sign-on include: Mitigate risk for access to 3rd-party sites ("federated authentication") [4] because user passwords are not stored or managed externally; Reduce password fatigue from different username and password combinations; Reduce time spent re-entering passwords for the same identity [4]
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 and password joined by a single colon :. It was originally implemented by Ari Luotonen at CERN in 1993 [1] and defined in the HTTP 1.0 specification in 1996. [2]
