Unable to load config info from /usr/local/ssl/openssl.cnf on Windows

While using OpenSSL on Windows:

openssl genrsa -out privatekey.pem 1024 -->

Created successfully

openssl req -new -x509 -key privatekey.pem -out publickey.cer -days 365 
---->

Showing error message as

unable to load config info from /usr/local/ssl/openssl.cnf

After installing OpenSSL I was required to create a new environment variable:

• Name: OPENSSL_CONF
• Value: C:\Program Files\OpenSSL\openssl.cnf

In powershell:

$env:OPENSSL_CONF = "${env:ProgramFiles}\OpenSSL\openssl.cnf"

This value differs from previous installation versions (as seen in a previous edit of this post). Also, don't forget to add the openssl binary folder ${env:ProgramFiles}\OpenSSL to your Path.

You should specify the absolute path to the config, something like this:

openssl req -x509 -config "C:\OpenSSL-Win64\bin\openssl.cnf" ...

In Windows 10, no need to restart nor run in Administrator's mode but instead set openssl config like so:

set OPENSSL_CONF=C:\Program Files (x86)\GnuWin32\share\openssl.cnf

Of course, if you are using GnuWin32
