[john-dev] Argon2

[Solar Designer]

Hi Agnieszka,

Please create a CPU format suitable for merging into bleeding-jumbo,
using latest code from:

https://github.com/P-H-C/phc-winner-argon2

This tree readily includes a hash encoding, so you no longer need to
invent your own encoding.

I'll post a separate message later regarding possible GPU optimizations.

Thanks,

Alexander

Or two: 2d and 2i.

That's fine. For next steps, I think before you approach GPUs again,
it'd make sense for you to experiment with the same optimizations on
AVX2 and MIC - that is, trying to make use of the 2x and 4x wider
vectors with explicit SIMD intrinsics inside the per-block function.
