AES is symmetric.

As of the OP's issue, note 369369.1 on MetaLink describes steps to add and load third-party providers to the Oracle VM. Also, the note states that there was a bug in 10.2.0.1 (bug #4475814) that prevented thirdparty  providers from working inside the Oracle VM, which is fixed in 10.2.0.2. In 10.2.0.1, only SunJce is supported. However, since SunJce supports RSA, I don't see an urgent need to load Bouncy Castle and go through the bouncing hassle of applying the patchset and then following the note 369369.1 to make it work... :)
