This is to me a good reason not to make --provider. We already now have a soon-to-be-dead parameter in --engine that we have to maintain for most of eternity, and there are no guarantees that OpenSSL 4 won't deprecate providers in favor of a new name (with some level of devils advocate involved). Tying curl parameters to backend specific constructs risks building up an unwieldy set of parameters where only small disjoint sets apply to non-EOL'd specific versions. > That's pretty much what I meant. Why not repurpose curl's --engine option for > "providers" when using OpenSSL 3? There is the risk that a rogue actor could subvert an application by adding an OpenSSL provider during an upgrade with the same name as a previous engine. Now, attackers with access to doing that are of course probably able to do worse things due to system privileges, but this could be a passive hard-to- detect vector. That being said, I'm not sure I have too many better ideas at the moment. -- Daniel Gustafsson https://vmware.com/ -- Unsubscribe: https://lists.haxx.se/listinfo/curl-library Etiquette: https://curl.haxx.se/mail/etiquette.html
