It may be a network problem. After adjusting the network here, it is normal.

auto_updater/bin /generate_keys.dart Finally, this was executed windows/WinSparkle-0.8.0/bin/generate_keys.bat

I tried using this method to resolve the issue and successfully fixed it. I hope it helps you.

The issue might be caused by using OpenSSL. First, you need to install OpenSSL (I didn’t use Chocolatey(It may be because if you use Chocolatey to install it, it will automatically add the path to openssl to the environment variable.); instead, I downloaded Win64 OpenSSL v3.3.2 EXE from this link).

Next, you need to set the OpenSSL executable in the environment variables, making sure that when you run dart run auto_updater:generate_keys, it can utilize OpenSSL to generate keys. (I added C:\Program Files\OpenSSL-Win64\bin to the system environment variable PATH, as openssl.exe is located in this directory.)

After that, running dart run auto_updater:generate_keys should work!

I hope this helps you resolve the issue!
