Answer 1

Have you tried this:

NSData *cont=[[NSData alloc]initWithBytes:[blob_data bytes] length:[blob_data length]];

and then convert data into NSString using NSString initWithData .

I will suggest you to do encryption AES 128 and after that compression gzip in order to reduce the bandwidth wastage. Also it also make your data secure.At the server side do this in reverse order you will get origional plain data.
