        We examine the problem of deciphering a file that has been Huffman
        coded, but not otherwise encrypted.  We find that a Huffman code can be
        surprisingly difficult to cryptanalyze.  We present a detailed analysis
        of the situatioin for a three-symbol source alphabet and present some 
        results for general finite alphabets.
