I'm using OpenSSL v1.1.1g on a Windows 10 machine (I don't know Linux - yet). Can Windows CMD/DOS commands be used in the OpenSSL configuration file or is the configuration file limited to the use of OpenSSL commands only? I assume the answer to this question is "No" since OpenSSL uses its own parser to process OpenSSL configuration files, but I'd like to have my assumption confirmed.
openssl.exe
