This is in python2.5: zipfile.py SVN rev-56308 When testing a zipfile.Zipfile().read() with a password protected zip file, I would continually get exceptions. So I tracked this down to line 796-797: if ord(h[11]) != ((zinfo.CRC>>24)&255): raise RuntimeError, "Bad password for file %s" % name scope related data: bytes = `)¶G\x02ùû¬&\x1E#çÕ` h[11] = ` ̄` zinfo.CRC = `1554440319` ord(h[11]) == 175 ((zinfo.CRC>>24)&255) == 92 When I commented out the error check, the script extracted 150 JPGs with no corruption or errors in any of the images...so its just seems like an issue with the error check.
