So I guess it used OpenSSL to figure out what was wrong with people's certificates. Not sure what it used that relied on internals so heavily it was hard to upgrade, or if the public interface just changed a lot.
Even with that, seems there was multiple issues that "prevented" ("made it harder than justifiable" rather) the author from keeping the project up, not just regarding OpenSSL.
