Secure Strings in Powershell

Greg Moore shows how to build out secure strings in Powershell:

One of the more common problems I’ve faced with a particular client is setting up data extractions from outside sources such as SFTP servers. Since this client deals with PII data, it’s essential that this is done in as a secure manner as possible. For example, all connections need to be encrypted using protocols such as SFTP instead of FTP.

Securely connecting is particularly easy to accomplish if one uses a 3rd party module such as Posh-SSH. However, you are still stuck with the problem of logging into the remote SFTP server securely.

Keeping credentials secured is something which Powershell makes pretty easy. I can’t think of a reason why you’d ever need to keep credentials in plaintext here.
