Subject: Keychain format speedup on CPU.


With the following commit Keychain format is now 2.4x faster on CPU
and scales almost linearly. However, Passware Kit Enterprise 11.7
achieves a speed of roughly 2,300 c/s whereas our plug-in achieves
1,513 c/s (thanks to Lukas).

Can we beat Passware? What are the possible optimization in Lukas
code? Can SSE acceleration be used (salt size is 20)? Thanks!
