Sorry for the stupid question.
But how can I import private key found by Pollard's kangaroo ECDLP solver? E.g. 0x60F4D11574F5DEEE49961D9609AC6
Electrum does not recognize it.
Make it size of 256 bits.
0000000000000000000000000000000000060F4D11574F5DEEE49961D9609AC6
and put it in wallet details as example on
www.bitaddress.orgDon't input your private key on a website. This is a security practice.
While there doesn't exist a convenient program that you can run offline and convert a hex private key with it, there does exist scripts like
this one you can run in a Python shell (vouching for this one in particular because I myself am using it in my code).
