Private Key -> ONE WAY hash -> Public Key -> ONE WAY hash -> Address
I know you know and that you've just made a typo, but for the sake of other users reading this thread, private key to public key is via a one way elliptic curve multiplication, not a one way hash.
Thanks for the heads up... yeah, was typing slower than I was thinking and my brain had already moved to the "one way hash" part of Pubkey -> Address which is where the OP seemed to be getting stuck
I've corrected it now.
