Satoshi signature challenge

1. create a character

2. name it, only hex characters are allowed (e.g. badface, deadfeed)

3. create an ID from the name (32 bytes, hex, e.g. id = name + random hex number)

4. find a valid signature from one of the Satoshi addresses for this ID ( 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa , 1K8SfPfTkvjF8YHGG134uQvjcdNDHM6UfB, 12cbQLTFMXRnSzktFkuoG3eHoMeFtpTu3S, etc.)

5. publish it

if this is possible Huh

Can you share your code?

i give you test z = 0xdead007000000000000000000000000000000000000000000000000000000002 make valid z r s from 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa

ok just need some time my old c64 is working on it
there seems to be a small problem with the code, it removed the 0s from z, I will fix it
