Does Java use AES-NI when available?

I just heard of the instruction set extension AES-NI. Does Java's JIT compiler compile the application to use AES-NI if it is available to enhance performance?

And if yes, does it also do so if it is not sure that AES will be used (like when using TLS)?

Solution

  • I think it's not bundled with JDK, you have to download and build it yourself
