452*** You seem to configure gvpe with OpenSSL 1.1 or newer.
453*** While this probably compiles, please note that this is not only
454*** unsupported, but also discouraged.
455***
456*** It is recommended to use either OpenSSL 1.0, as long as that is still
457*** supported, or LibreSSL (https://www.libressl.org/).
458***
459*** This is not a political issue - while porting GVPE to the newer
460*** OpenSSL 1.1 API, I encountered two incompatible API changes that were
461*** not documented, were not caught while compiling but caused security
462*** issues. When reported, the reaction of the OpenSSL developers was to
463*** update the documentation.
464***
465*** As a result, I lost all confidence in the ability and desire of
466*** OpenSSL developers to create a safe API, and would highly recommend
467*** switching to LibreSSL which explicitly avoids such braking changes.
468***
469*** WARNING WARNING WARNING WARNING WARNING WARNING WARNING
