public string Encrypt ( string plainText ) { if ( plainText == null ) throw new ArgumentNullException ( "plainText" ); //encrypt data var data = Encoding . Unicode . GetBytes ( plainText ); byte [] encrypted = ProtectedData . Protect ( data , null , Scope ); //return as base64 string return Convert . ToBase64String ( encrypted ); } public string Decrypt ( string cipher ) { if ( cipher == null ) throw new ArgumentNullException ( "cipher" ); //parse base64 string byte [] data = Convert . FromBase64String ( cipher ); //decrypt data byte [] decrypted = ProtectedData . Unprotect ( data , null , Scope ); return Encoding . Unicode . GetString ( decrypted ); }
