public abstract class Provider
extends Properties

This class 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 it is installed in.

There is a default provider that comes standard with the JDK. It is called the SUN Provider. See The Provider Class in the "Java Cryptography Architecture API Specification & Reference" for information about how providers work and how to install them.

Provider(String, double, String): Constructs a provider with the specified name, version number, and information.

clear(): Clears this provider so that it no longer contains the properties used to look up facilities implemented by the provider.
getInfo(): Returns a human-readable description of the provider and its services.
getName(): Returns the name of this provider.
getVersion(): Returns the version number for this provider.
put(Object, Object): Sets the key property to have the specified value.
remove(Object): Removes the key property (and its corresponding value).
toString(): Returns a string with the name and the version number of this provider.
