Ok, lets test your script without you revealing it to the public, just drop the first 2 characters on the left for this public key's private key :
03cefd304a9a8da40666e97b2d9650e31a71a9a9fcd29a24724d31a2fabbc8ea0e
Do you need the exact range or not? It has 32 characters and it starts with F, just drop the second character and give me the public key for it to verify, that could help a lot for others to believe you.
I did not understand your proposal very well regarding the range of your pk
but for example if you eliminate the first 2 digits of your pk in decimal and generate another pubkey you will possibly get a pubkey that starts (although I recommend explaining the range better):
1= 03941029...
2=02caf96e4..
After I know what your pubkey is, I get the rest of the digits.
without the need to generate millions of keys.
I was very clear, I gave you my public key, and my private key has 32 hex characters starting with F, I just want you to drop the second character with your first try since there are only 16 possible answers, if your script works, you should be able to drop the second char from my private key.
Only hex, I don't work with decimal or binary.
I think you misunderstood my point, if I was able to know the second character easily ecc would be broken.
to know the first digits you would need to know pk2.
all this without the need to save millions of results.
my problem is that my computer basically runs out of power to reduce more. due to stress and hangs
