black256-14-rnd is blake2s
Are you sure its the same?
for BLAKE. Based on the security analysis performed so far, and on reasonable assumptions
on future progress, it is unlikely that 16 and 14 rounds are meaningfully more secure than
12 and 10 rounds. Recall that the initial BLAKE submission [1] had 14 and 10 rounds,
respectively, and that the later increase [2] was motivated by the high speed of BLAKE.
This change gives a direct speed-up of about 25% and 29%, respectively, on long data.
Speed on short data also significantly improves.
