Report on a first-pass, for what it is worth:
Byte distribution analysis reveals a histogram that is approximately uniform although I have not yet calculated any confidence intervals. Double-byte
or n-gram analysis may be useful, as may be an autocorrelation analysis, but I am too tired to write any more code tonight. Maybe tomorrow.
The bottom line is that the data set appears to have a high entropy level. This is consistent with either the hypothesis that this is merely random
junk or the hypothesis that it is the ciphertext resulting from a reasonably modern block cipher.
The file does not appear to contain a header, at least not one that fits any paradigm I am familiar with. Thus, I think I can safely say that it is
not a Windows executable, nor a Word document, Excel spreadsheet, etc.
