I get prompted with the option descriptions.
After running this
openssl pkcs12 -in path.p12 -out newfile.key.pem -nocerts -nodes
I get prompted with "Enter Import Password:". What is this import password? I tried the one I set from the firefox backup and it responded with "Mac verify error: invalid password?". I'm sure that the password is correct because I tested it by importing it again into firefox.
I got the commands from the answer to this question!
