password

An easy and secure way to store a password using Data Protection API

If you're writing a client application that needs to store user credentials, it's usually not a good idea to store the password as plain text, for obvious security reasons.

Obviously you will need the key to decrypt the password, so it needs to be either in the executable or in the configuration.
