Thanks! I'd love to see this library become usable behind a command line flag or config setting. At some point we're going to want to switch to it. I believe the main issue at the moment is the malleability issues? If so, it would seem possible to use OpenSSL to parse the signature into

Can this be combined with the ideas on deterministic signing to show matching signatures with OpenSSL's implementation?Not sure if that's worth much, since we would just be testing needles in a very large haystack, but better than nothing?On Wed, 09 Oct 2013 20:50:30 -0700, Warren Togami Jr.
