Actually, that might be outdated. I grepped the xlrd source for this
particular exception. It's raised only from once place: xlrd/book.py:896
(assuming you're using the latest version: 0.9.3). The particular function
'handle_filepass' is weird...:
def handle_filepass(self, data):
if self.verbosity >= 2:
logf = self.logfile
fprintf(logf, "FILEPASS:\n")
hex_char_dump(data, 0, len(data), base=0, fout=logf)
if self.biff_version >= 80:
kind1, = unpack('<H', data[:2])
if kind1 == 0: # weak XOR encryption
key, hash_value = unpack('<HH', data[2:])
fprintf(logf,
'weak XOR: key=0x%04x hash=0x%04x\n',
key, hash_value)
elif kind1 == 1:
kind2, = unpack('<H', data[4:6])
if kind2 == 1: # BIFF8 standard encryption
caption = "BIFF8 std"
elif kind2 == 2:
caption = "BIFF8 strong"
else:
caption = "** UNKNOWN ENCRYPTION METHOD **"
fprintf(logf, "%s\n", caption)
raise XLRDError("Workbook is encrypted")
Is that function only handling encryption if verbosity is greater than 2?
