## Create AES key with random data and export to file
<#
Sometimes a script needs to use a password, but you want it stored securely.  Passing a credential by utilizing 2 things:

1.	A password file that contains the encrypted file
2.	A key file that contains a randomly generated AES key

allows for utilization of credentials within scripts by different users and servers.  
**The following method is only as secure as the locations of the files(password and key) themselves.**
