public abstract class Provider

extends java.util.Properties

Represents a provider for the Java Security API. A provider implements some or all parts of Java Security, including:

• Algorithms (such as DSA, RSA, MD5 or SHA-1).
• Key generation and management facilities (such as for algorithm-specific keys).

Each provider has a name and a version number, and is configured in each runtime in which it is installed. The default JDK provider is the SUN Provider. See The Provider Class in Sun's Java Cryptography Architecture API Specification & Reference documentation for information about how providers work and how to install them.
