I have some functions in Python and it runs very slow compared to C.
The sage I want to do with the GPU is as follows
Pr = 115792089237316195423570985008687907853269984665640564039457584007908834671663
E = EllipticCurve (GF (P), [0,7])
N = E.order ()
G = E(55066263022277343669578718895168534326250603453777594175500187360389116729240,32670510020758816978083085130507043184471273380659243275938904335757337482424) # on E

numInt = 5646546546563131314723897429834729834798237429837498237498237489273948728934798237489723489723984729837489237498237498237498237498273493729847
numMod = numInt %N
numInv = pow(numMod ,N-2,N) # detail -> https://stackoverflow.com/questions/59234775/how-to-calculate-2-to-the-power-of-a-large-number-modulo-another-large-number
numMod * G
numMod * T
(T-G) * numInv
print (5*T)
print (2*G)
print (numMod * G)
print (numMod * (-G))
print (numMod * T)
print ((numMod-3) * (T-G))
Do you have any suggestions? What should I do ?
I wrote my question here because it is indirectly related to this project. Please forgive.
Hi! The slowest part in your python is inverse function. Try to implement gmpy2 inverse function (included in gmpy2) - it is C-based and very fast:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#gmpyYou can find the details here:
https://bt.irlbtc.com/view/5245379.msg55214449#msg55214449When using Python, I use FastEcdsa(
https://github.com/AntonKueltz/fastecdsa) library and mathematics similar to Sage. But can I do the math faster? I want to understand.
The FastEcdsa Library is fast, but I don't know if it uses the gmpy2 you suggested. My python script uses 17% of the CPU as a result. I wanted to write with Anaconda (for GPU), but I could not find a gpu running as fast as C or I could not.
Thank you MrFreeDragon .
No. you can't be faster then GPU on your CPU.
if i explain your word in easy example commands for new gpu based develop application/repo, by jean luc or other developer, could be develop, or if any one know already developed can post links and refferance
here are some example aspected commands
./vs-pub -c -gpu -input in.txt -output out.txt -add 0250863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B2352 #pubkey
./vs-pub -c -gpu -input in.txt -output out.txt -mul 123456789 # its privatekey in num (not hex)
./vs-pub -c -gpu -input in.txt -output out.txt -sub 0250863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B2352 #pubkey
./vs-pub -c -gpu -input in.txt -output out.txt -sub 0250863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B2352 -r (reverse like
02508... pubkey substract to all listed pubkey inside in.txt
-c is compressed pubkey
-u is uncompressed pubkey
-input is load of compressed/uncompressed pubkeys list
-output is results output to file
-r is reverse of sub ( listed pubkey in command minus(-) in.txt (pubkeys)
