It COULD be base 64, but it could be other things too. For example,
each two digits could represent the hex representation of an ASCII
digit, which would give:
which is gibberish. Decoding properly depends on how it was encoded.
Do you know how it was encoded?
Perhaps, it's a picture ....
Not likely, given how few unique combinations there are. It would be an
extremely low resolution picture. *IF* my math is correct, out of the
10168 characters that David provided, there are 16 unique bytes (0-10
and A-F, i.e. hex), 43 unique 2-byte combinations (out of a possible
256), 143 unique 4-byte combinations (out of a possible 65,536), and 254
unique 8-byte combinations (out of a possible 4,294,967,296). Not
enough unique combinations to represent enough different pixels.
Sorry, I should add that there are actually only 5084 2-byte
combinations, 2542 4-byte, and 1271 8-byte, so those are the maximum
number of possible combinations given the short length of David's data
(it would be a tiny picture). The larger numbers above are the maximum
number of POSSIBLE combinations, given a large enough data set. Still,
the number of actual combinations relative to 5084/2542/1271 is pretty
