Accelerate core functions with SIMD intrinsics
Some core computation functions like sha256, bloom (and some others maybe) are implemented as per standards.
To gain more computation speed, SIMD instructions accelerated implementations of these functions could help. For instance, we know a SIMD accelerated version of sha256 is used by the bitcoin-core client. And for reference, some accelerated versions like sha256-simd have obtained up to 8x improvement compared to a standard implementation.
We Need to Go Deeper.
We Need to Go Deeper.
Yes you are right, just now im implementing the Jean Luc Pons SECP256K1 library, that work in very similar way than the libgmp, but it use some group Modulo Operations with SSE2 Operations to boost his speed to create publickeys up to 5 times faster. This will boost all the speed from all modes from address to bsgs mode.
Once that i finish that part i will try to implement your suggestion with that version of sha256.
Best regards
I just add some of this code, it help to speed up x2 the RMD160 mode
Great, but I can't build the latest commit with mingw. here is the error report:

mingw32-make: *** [Makefile:18: default] Error 1
I need to check this closely, there are others users that actually report this.
Regards!
@albertobsd Having the same issue sadly. Using Msys2 on Windows10 which worked with mingw32/64 before fine. But the latest didn't. I also added some fixes for Windows. In some files you have to add the line:
#define __STDC_FORMAT_MACROS 1
When I can help you with anything, let me know.
For me it happens only in that hash/ripemd160_sse.cpp file
I made it an double array like here, and it compiles correctly. Mabe we had to try if it works correctly as well:

Excellent, thanks for sharing, to check if it is working welll you can run this test:
./keyhunt -m rmd160 -f tests/1to32.rmd -r 1:FFFFFFFF -l compress
The will check if the rmd output is OK or not, is in the readme https://github.com/albertobsd/keyhunt#rmd160-mode

Sadly i can't test it, cause it seems there are other issues as well. So after changing what I have stated above, there are rising multiple different errors from other files, so no easy way for now to fix them.
