The '''Java Cryptography Extension''' ('''JCE''') is an officially released Standard Extension to the [[Java Platform]] and part of [[Java Cryptography Architecture|Java Cryptography Architecture (JCA)]]. JCE provides a framework and implementation for [[encryption]], [[key generation]] and [[key agreement]], and [[Message Authentication Code]] (MAC) algorithms. JCE supplements the Java platform, which already includes interfaces and implementations of message digests and [[digital signature]]s. Installation is specific to the version of the Java Platform being used, with downloads available for [http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html Java 6], [http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html Java 7], and [http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html Java 8]. "The unlimited policy files are required only for JDK 8, 7, and 6 updates earlier than 8u161, 7u171, and 6u181. On those versions and later, the stronger cryptographic algorithms are available by default."<ref>{{Cite web |title=Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files Download |url=https://www.oracle.com/java/technologies/javase-jce-all-downloads.html }}</ref>
