Is there any way on standard Windows Server (such as with certutil?) to decrypted a pkcs8 pem encrypted private key?
i.e. What is the equivalent on windows of:
openssl pkcs8 -in key.enc -out key.pem
I tried looking through certutil doc for ages and cannot figure out any way to do it.
Implentation of such tool is lacking inside Windows. I would suggest to just install the openssl library port for Windows inside your server. Your command would be the same after too.
Get it from there; Win32/Win64 OpenSSL, or more source listed here; Binaries.
The 'official' Microsoft ecosystem way is to use a tool called PVK2PFX, which for some reason is only included in Microsoft SDK, and not in general windows releases.
