Yes. Commandline does support the -twopass option to make the MAC password for 1 different from 3 (or 2 and 3), or you can simply ignore the password for 1 on reading using -nomacver. What makes it even more confusing: passing option -nodes to the openssl command doesn't ask the pass phrase anymore (as expected) but still shows the private key, this time not encrypted anymore. Where pkcs12 is the openssl pkcs12 utility, -export means to export to a file, -in certificate.pem is the certificate and -inkey key.pem is the key to be imported into the keystore.
