(Go) Duplicate openssl pkcs12 –export –in certfile.cer –inkey certfile.key –out certfile.pfx

How to create a PKCS12 (.p12 or .pfx) from a certificate file and private key file: Demonstrates how to duplicate this OpenSSL command:

Duplicate openssl pkcs12 –export –in certfile.cer –inkey certfile.key –out certfile.pfx
