Use fastecdsa library

[Nimrod-Galor]

I love this script thanks for sharing.
How about using fastecdsa library?

[imcmurray]

I asked the very same question to myself a few days ago. Submitted pull request #119

Cool, thanks for sharing
What os you are using?

On Windows 10 I receive some big error when I try to install fastecdsa

[Nimrod-Galor]

Installing fastecdsa on windows is a mess.

Cannot open include file: 'gmp.h': No such file or directory

Yikes - forgot about including information about how fastecdsa needs GMP. Anybody want to tackle installing that on Windows? https://gmplib.org/ It looks a little steep. I'm running Debian based (Ubuntu 18.04) and GMP was a straight forward install.

For RedHat, Debian and MacOS users: http://www.mathemagix.org/www/mmdoc/doc/html/external/gmp.en.html

I succeed to run it on Ubuntu 18.04 LTS. I will check to see if I can run it also on windows.

Thanks @imcmurray

I've tried implementing fastecdsa in previous versions of this program, and I agree that it is faster. But I've also spent countless hours trying to port GMP into a windows compatible library.

I want this program to be platform independent. Because it still is a proof-of-concept, I just want it to be able to run anywhere. So I chose the next best option which is starkbank-ecdsa. Theoretically, it is impossible for this program to be successful, this program is just for fun, I look at it like a fun-pointless side project. So limiting which operating system it can run on takes away from the fun, because not as many people are able to use it.

Like i said, I tried and failed to port GMP to windows a couple months ago when I attempted to implement fastecdsa. If you can find a way to do, then I'll commit your pull request.

Thanks again

You're right @Isaacdelly this is a fun side project, almost like digging for gold with a blindfold!
I totally understand your direction and wishes with this project. Maybe somebody down the road will come up with a solution for the Windows GMP issue - maybe Windows 10 insider edition would be a good target for somebody to take another bite - anybody up for the challenge? LOL

Read this, thought.. "hey why not give it a whirl?" and now I regret it. keyboard throwing, snapping at everyone, muttering to myself like someone pushing a grocery cart down an alleyway kinda regret.. and then I went "wtf am I doing?!?!?! this was a lark in the first place!" aaaaand I feel better now having quit trying and telling myself I will never ever ever ever even look at GMP from a windows perspective... okay I'll admit one day I'll get bored and think "Hey why not?" and when that day comes I sure hope I remember this post right here! :)

Thanks for brightening my day @Finn-Sionnach with your descriptive expressions, I'm going to be chuckling over your response for a while. GMP on Windows - so much craziness indeed!

You rose to the challenge, accepted it's whims and mythical number crunchiness, but as many before you, got a little too close to the Sun and realize WTF am I doing? LOL
Come - join the rest of us that dared to venture a little too close! You're in good company my friend.

It is working on windows 10 with FASTECDSA just read in it here: AntonKueltz/fastecdsa#11
Even a beginner and no programming skill like me successfully run the plutus-fastedcsa on windows 10 just a couple of minute ago.

[OSoup]

Fuck it. I lost another hour of my life with this fastecdsa on windows shit with no result. @naphy0 if you succeeded please put the exactly steps. What version of python do you use?

Sorry late reply.

You need to have an microsoft visual 2019 and Microsoft c++ in visual studio
to run the fastedcsa. You cannot install it without Microsoft c++. after that follow this instruction.

1. Download https://github.com/ChillMagic/MPIR-Binary
2. Download https://github.com/AntonKueltz/fastecdsa
3. rename mpir.h to gmp.h from MPIR-Binary-master\include and rename mpir.lib to gmp.lib from MPIR-Binary-master\lib\MD\x64\Release
4. Copy and paste gmp.lib C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.21.27702\lib\x64
5. Copy and paste gmp.h C:\Phyton3\include
6. I don't remember if I do this ( just put mpir.dll from MPIR-Binary-master\dll\x64\Release in to the directory of package, C:\Python37\Lib\site-packages\fastecdsa ) Do it last if you have error. if not working try to rename it again to gmp.dll But I guess it's not needed to install fastedcsa.
7. Open CMD and cd to where you put your fastecdsa E:\Download\fastecdsa-master
8. when your cmd is in the directory type: python setup.py build
9. after installation type again: python setup.py install
10. Good Luck treasure hunting. Give me and the creator some tip you find one 3LkF5XDiEvW9xbVLAcjPHmq4JL9QPEUNYR

If there is an problem, message me here again.!! Happy hunting. I have a problem my PC cannot handle this program it hang. I wonder if I can lower the power to my CPU. I am using laptop i7-3632QM @ 2.20GHz and 8GB RAM.

I am using Python Latest

From what I see the generated addresses are uncompressed. What we have to change in the code to search compressed addresses? or both? Thanks!

[ilyacherevkov]

I've just spent 2 days running this on 12 cores + 16 gb, burning electricity and my hardware :)

By the way, is it ok this implementation uses 500 mb RAM per core, and old one was using 2gb if I m not mistaken?

[Isaacdelly]

I'm pinning and closing this issue for now. Thanks for @imcmurray for the time he invested.
