I don't think that's how base 64 encoding works. To the best of my
knowledge, base 64 encoding simply uses a subset of ASCII characters to
represent binary data. I could type a bunch of characters in using those
characters, and convert it to binary data, although it might not represent
something useful.
I'm oversimplifying a bit here, I suspect, since there are limitations on
the number of characters per line requiring hard returns within the data,
you'd have a certain number of characters, and so on, but the fundamental
problem remains, I think.
