The curl project is happy to introduce official and blessed curl builds for Windows for download on the curl web site.
This means we have a set of recommended curl packages that we advice users on Windows to download.
On Linux, macOS, cygwin and pretty much all the other alternatives you have out there, you don’t need to go to random sites on the Internet and download a binary package provided by a (to you) unknown stranger to get curl for your system. Unfortunately that is basically what we have forced Windows users into doing for a few years since our previous maintainer of curl builds for Windows dropped off the project.
These new official curl builds for Windows are the same set of builds Viktor Szakats has been building and providing to the community for a long time already. Now just with the added twist that he feeds his builds and information about them to the main curl site so that users can get them from the same site and thus lean on the same trust they already have in the curl brand in general.
These builds are reproducible, provided with sha256 hashes and a link to the full build log. Everything is public and transparently done.
All the hard work to get these builds in this great shape was done by Viktor Szakats.
This is handy and very much appreciated!
