Automated MEK key generation

Hello, I'm currently trying to automate the generation of an RSA key pair (public/private), but having difficulty doing so. I can write a batch file to begin the process, however, it then asks a series of questions (name, locality, etc), and for the life of me, I cannot work out how to make the batch file answer the questions.

I've done something similar a coupe of days ago, for automatic generation of an SSL key, and I was able to make it answer the questions by assigning values to the respective variables. I assumed that it would be a similar method for RSA key pair, though the solution seems to be escaping me.

I hope you can help.

Thanks for your time,

Seb
