Data you didn't compute yourself isn't supposed to contain anything
known. Each and every bit may contain something you didn't expect,
that's why you have to do input checking.

The most you can do with your externally fetched data is printing it
out, byte by byte, in hex. "Assuming" that this'll make up any
well-known data formats is just asking for trouble.
