Hello all, After working on various flavors of SHA over the past week, I noticed there is a fair amount of duplication, not only of true boiler plate but also of glue code that is not entirely non-trivial. So this series proposes a way to cut down on that: I implemented generic glue for SHA-256 and SHA-512, and ported the generic implementations to use it. The last two patches are examples of non-trivial uses of it. Patch #5 ports the arm64 SHA-256 Crypto Extensions to use it: this code needs to enable and disable the NEON before and after using it, and has an implementation of the padding in asm for inputs that are round multiples of the block size. The final patch is the same core code as the patch I sent yesterday, but this time with most of the redundant glue removed. Comments, suggestions etc are highly appreciated! Regards, Ard.
