*** 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 |

*** WARNING WARNING WARNING WARNING WARNING WARNING WARNING |
| 470 |

*** Again, do not use OpenSSL 1.1 and complain if stuff breaks. |

*** You have been warned, but your choice is respected. |
