Description

Hi,

Thanks to mkcert for providing us a great tool for multiple environments. Anyone, could you please give me a hint why I am getting the below error. The background is, I have a node js application which is taking help of mkcert to create a CA for Windows. While starting the nodejs app, it ended with the error

(node:2192) UnhandledPromiseRejectionWarning: Error: Command failed: SET CAROOT=C:\Program Files (x86)\Test\cert && "C:\Program Files (x86)\Test\cert\mkcert-v1.3.0-windows-amd64.exe" -install -cert-file "C:\Program Files (x86)\Test\cert\localhost.crt" -key-file "C:\Program Files (x86)\Test\cert\localhost.key" localhost Created a new local CA at "C:\Program Files (x86)\Test\cert" 💥 ERROR: add cert: Failed adding cert: The request is not supported.

Notes:

  • I have customized the CARROT.
  • while looking at the mkcert code, the error is thrown by truststore_windows.go at addCert, which is internally calling crypt32.dll. I am not sure what is going wrong with crypt32.dll . @FiloSottile , could you please have a look at this. Thanks,

Research direction
Investigate truststore windows.go, specifically the addCert function that calls crypt32.dll. Determine why Crypt32.dll returns 'The request is not supported' on Windows, possibly due to permissions or custom CAROOT path. Check if the issue is reproducible with the latest mkcert version.
