462***
463*** This is not a political issue - while porting GVPE to the newer
464*** OpenSSL 1.1 API, I encountered two incompatible API changes that were
465*** not documented, were not caught while compiling but caused security
466*** issues. When reported, the reaction of the OpenSSL developers was to
467*** update the documentation.
468***
469*** As a result, I lost all confidence in the ability and desire of

471*** switching to LibreSSL which explicitly avoids such braking changes.
