If when attempting to create a Certificate Signing Request, (CSR) using Apache and OpenSSL you receive this error;
Unable to load config info from /usr/local/ssl/openssl.cnf
This is a Unix path structure and not Windows. To remedy this your command will have to be a little longer;
openssl req -new -key my.key -config "C:\Program Files\Apache Software Foundation\Apache2.2\conf\openssl.cnf" -out my.csr
Amending the command to suit the titles of the key and csr file.
