RSA cryptography between Python and Java

I've created an RSA key in Java. I have exported the public key by making it into a X509EncodedKeySpec and spitting out the result of getEncoded(). I want to use this public key to encode something in python that I will send to Java, and then decode in Java with the corresponding private key. A

I read in this thread lots of different (hopefully personal) opinions on the question of Java vs Python, so I thought I will post mines too (with the amendment that I am a Java guy, spending there more than 10 years). I don't think you can do a performance comparison upfront (without having it com

Thanks for these suggestions. To be clear, we already have a Python 2.4 minimum requirement for other reasons, and we are looking for a long-term solution so that as Python advances, the scripting solution can keep up in a timely way. Since the Java code is for a very large, complex application,

For most purposes Jython 2.1 is just fine. The lack of recent features is not a show stopper. What do you need metaclasses? decorators? BTW, there is Jython 2.2 as an alpha release. There are a number of ways you can use Java code through Python. Use JPype to start a Java VM http://jpype.sourcefo
