I am creating a script that changes important account information, including passwords and usernames, but I can't take the input from a user at runtime. I could get the script to work with the information included in variables, but that is a security risk we want to avoid. As far as I can tell, _Crypt_HashData or possible _Crypt_EncryptData are how I would go about this. I looked at the help file and I am struggling to understand the implementation. Do I need an external document with the info? That would present the same issue. Do I need to create the variable and then run the function in another script and then add it in? I am quite lost. Could somone give me a basic step-by-step rundown?
