rails run shell command with user input

I want to run shell command from rails app controller.
My app code is:

cmd = "openssl genrsa -des3 -out testfolder/testkey.key 1024"

system cmd

than shell will ask me password, so if you run this command from terminal you can input password, but if I run from controller I can't.

I don't want to use rails OPENSSL, for some reasons.

I tried to google but I have no result.

Also I tried something like this:

cmd = "openssl genrsa -des3 -out testfolder/testkey.key 1024"

system cmd

system 'echo', '111111Passs'

This is not solution of my problem.

My question is:
how to pass password from controller to shell?
Than how I can submit this command? (simulate press on ENTER on my keyboard)

Thanks

Please can you write example ? it will be something like this ?: cmd = "openssl genrsa -des3 -out testfolder/test.key 1024 -S 111111Password"

You can try passing the passphase through an argument (not recommended):

openssl genrsa -des3 -out testfolder/testkey.key -passout pass:SECRET_PASS 1024

A more secure option is to write the passphrase to a temporary file and use this:

openssl genrsa -des3 -out testfolder/testkey.key -passout file:passphrase.txt 1024

Answer shamelessly lifted from this SO thread which has much more detail and better explanations.
