public static string EncryptString( 
   DataProtectionStore keyStore,
   string plainText,
   string entropy
)

Parameters

keyStore

Specifies which key store to use (User or Machine)

plainText

A string of text to encrypt

entropy

The entropy, or "password" to use to decrypt this data. The value must be the same as was used to originally encrypt the data

It is important not to lose the entropy used to encrypt this data. If the entropy is lost, the data cannot be decrypted. If the entropy must be stored, do not store it with the encrypted payload.

 WARNING: The encryption produced by this class is only usable from the machine on which the encryption occurred. The encrypted text cannot be used by a different computer.
