How do I generate password GUID on with suitescript 2.x - netsuite

Question

I am new to suitescript, I have been trying to generate a passwordGuid but it gives me a plain text and I expected something encrypted.
I have configured a digital ocean droplet as a SFTP client.
Generated the private and public key
I am using this code provided by one of the guys but I always don't get the expected password Guid
