java.util.jar and cryptography
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.
