456*** You seem to configure gvpe with OpenSSL 1.1 or newer.
457*** While this probably compiles, please note that this is not only
458*** unsupported, but also discouraged.
459***
460*** It is recommended to use either OpenSSL 1.0, as long as that is still
461*** supported, or LibreSSL (https://www.libressl.org/).
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
470*** OpenSSL developers to create a safe API, and would highly recommend
471*** switching to LibreSSL which explicitly avoids such braking changes.
472***
473*** WARNING WARNING WARNING WARNING WARNING WARNING WARNING
