This document describes what you need to do in order to integrate your provider into Java SE so that algorithms and other services can be found when Java Security API clients request them.
How to add multiple values per key to a Java HashMap It seems like an oversight for the standard Java API not to have a collection class that allows a key to havemultiple values. If this is anapplication requirement, the three best ways to solve the ‘multip...
Applications do not need to implement security themselves. Rather, they can request security services from the Java platform. Security services are implemented in providers (see below), which are plugged into the Java platform via a standard interface. An application may rely on multiple independent...
