Find the corresponding public key via hash160.

For low bit bitcoin puzzles, such as 66 or 67, the public key can be used to quickly solve the private key via the Kangaroo algorithm without brute-force cracking. However, the public key is only leaked every 5 bits, so how do we get the public key for the lower puzzles? The answer is to find it through hash160.

When we know a bitcoin address, its corresponding hash160 is naturally known.By point addition of elliptic curves, we can quickly solve for the public key, which is much faster than scalar multiplication.

For puzzle 67, suppose a private key 40000000000000000, the corresponding pubkey is 041238c0766eaebea9ce4068a1f594d03b8ed4930d072d9c8b9164643e1516e6338a9db02dbb271359d6c979e2d1c3dc170946252dcc74022805cdb728c77b7805, by point add 1, publickey is 0414dad36d4491f7f00db31f074bbc77ef19ec7245a4d81f8f5b25e3707ee4dd09207528c7b30b70fea5839b3f10a5868e324b18fe7b67ad2a1397d55cc9704d0e, then calculate the hash160, in here is cd1577dd1559e362c85d360414e235d0e099540f, by performs point add operations without stopping, until hash160 is equal to puzzle 67's hash160 739437bb3dd6d1983e66629c5f08c70e52769371, we can get corresponding pubkey and put it in kangaroo to find private key.

You can directly use it or change num_processes to your want. It is made for puzzle 67.
