o be a X-Y coordinate (i.e. 0's at the same place in the digest: halfway through and at the end) while the digest produced by openssl is truly random. Am I misreading this or is this significant? Is the digest generated by openssl encoded in some sort of format or is it truly random as I expect? Tha
