    Default java.util.jar and cryptography

    Hi All,


    I am actually understanding the Android OS internals and I came across a part which needs to be clarified by Java people :)

    The package installer of Android uses java.util.jar.JarFile class which verifies the signature on Android Application Package.

    To understand this, I went to look up the java.util.jar.JarFile class which uses JarVerifier class to verify.

    And here I got lost.

    I don't see the cryptographic algorithms (RSA) called or the java JCE provider engine...

    Can somebody suggest the flow, so I can understand.

    Thanks.
