Is JCE part of Java SE 6?

I am trying to use some open source java library and that library has JCE as one of its dependencies. If I am using Java 1.6, do I need to download a JCE library separately or is it part of it? Seems like bountycastle.org (the open so开发者_如何转开发urce provider for JCE) does not have any JCE listed for 1.4+

JCE is bundled with JavaSE as of 1.4, according to JCA's documentation....

Notes on Terminology

Prior to JDK 1.4, the JCE was an unbundled product, and as such, the JCA and JCE were regularly referred to as separate, distinct components. As JCE is now bundled in the JDK, the distinction is becoming less apparent. Since the JCE uses the same architecture as the JCA, the JCE should be more properly thought of as a part of the JCA.

Yes it is part of Java 6.
