    for (NSInteger iIdx = 0; iIdx < [dataNames count]; iIdx++) {
      dataName = [dataNames objectAtIndex:iIdx];
      if (dataName.type == kDVDataTypeString) {

        NSString *thisStringValue = [dataVault getString:dataName.name];
      }
      else if (dataName.type == kDVDataTypeBinary) {
        // Stored value is of binary type
        NSData *thisBinaryValue = [dataVault getValue:dataName.name];
      }
      else {
        // Unknown type. Possibly stored using previous version of dataVault
        // Try as string first and then as binary
        NSString *thisStringValue = [dataVault getString:dataName.name];
        if (thisStringValue == nil) {
          NSData *thisBinaryValue = [dataVault getValue:dataName.name];
