Implementing Simple Encryption and Decryption with ProtectedData Class

Implementing Simple Encryption and Decryption with ProtectedData Class protecteddata Demonstrates how to implement simple encryption and decryption of data such as database strings with the new ProtectedData class. C# .Net Fun - http://www.dotnetfun.com - Michael G.

strDBString System.String The database string to encrypt. "Data Source=localhost; User ID=sa; Password=somepassword;" strFileName System.String The file name to which encrypted data is saved and read from during decryption. "ENCDBSTR.bin"

        byte[] arrUnencryptedDBString = ProtectedData.Unprotect(arrEncryptedDBString,
            arrEntropy, DataProtectionScope.CurrentUser);
        // Convert the byte array to a string:
        strUnencryptedDBString = System.Text.Encoding.Unicode.GetString(arrUnencryptedDBString);
    }
    // Return the unencrypted DB string:
    return strUnencryptedDBString;
