Hi deeztek,
I'm not familiar with PHP, but you can check how we generate SSHA512 hash with Python code here:

Also, what version of iredmail do I need to be to get the SHA512 password support?
The upcoming release, iRedAdmin-0.2.1 (open source edition). Of course upcoming iRedAdmin-Pro supports it too.
