Alternatively, you can download and install OpenSSL from the official website:
Using OpenSSL on Windows bridges the gap between different environments. Developers often use it to: openssl windows
Once installed, the functionality of OpenSSL on Windows mirrors its Linux counterpart almost entirely. Users can generate RSA private keys with openssl genrsa -out private.key 2048 , create Certificate Signing Requests (CSRs) using openssl req -new -key private.key -out request.csr , or self-sign certificates for internal testing. Another common task is converting certificate formats—for example, turning a PEM file into PKCS#12 for import into Windows Certificate Store using openssl pkcs12 -export -in cert.pem -inkey key.pem -out bundle.pfx . These commands are invaluable for Windows administrators managing IIS web servers, securing remote desktop connections, or automating certificate lifecycle management via batch scripts or PowerShell.
