The ConvertTo-SecureString cmdlet converts encrypted standard strings into secure strings. It can also convert plain text to secure strings. It is used with ConvertFrom-SecureString and Read-Host.

The secure string can be converted back to an encrypted, standard string using the ConvertFrom-SecureString cmdlet. This enables it to be stored in a file for later use. If the standard string being converted was encrypted with ConvertFrom-SecureString using a specified key, that same key must be provided as the value of the Key or SecureKey parameter of the ConvertTo-SecureString cmdlet.  Note Note that per DotNet, the contents of a SecureString are not encrypted on non-Windows systems.
