Hi!
Since the EasyRSA 3.0.6 version it's available new option --passin
It's will be great if you add this option to your function buildClientFull which located in Commands.php line 97
thank you

Hi! Thanks for this idea, can you provide an example of full shell command with this option? It's just that I haven't used this option before, and in general I haven't used easyrsa for a long time.
