python Programming Glossary: checksumPython: Inflate and Deflate implementations http://stackoverflow.com/questions/1089662/python-inflate-and-deflate-implementations To handle the raw deflate and inflate without header and checksum the following things needed to happen On deflate compress strip.. strip the first two bytes header and the last four bytes checksum . On inflate decompress there is a second argument for window.. see RFC 1951 http www.ietf.org rfc rfc1951.txt an Adler 32 checksum of the uncompressed data 4 bytes The C# DeflateStream works..

Detect duplicate MP3 files with different bitrates and/or different ID3 tags? http://stackoverflow.com/questions/476227/detect-duplicate-mp3-files-with-different-bitrates-and-or-different-id3-tags and ID3 tags that can be incorrect I know I can do an MD5 checksum of the files content but that won't work for different bitrates... know if ID3 tags have influence in generating the MD5 checksum. Should I re encode MP3 files that have a different bitrate.. files that have a different bitrate and then I can do the checksum What do you recommend python file mp3 duplicates id3 share..
http://stackoverflow.com/questions/5047494/python-crc32-woes function. Easy no The bzip2 format has a crc32 checksum for the file at the end. No problem binascii.crc32 to the rescue... binascii.crc32 to the rescue. But wait. The data to be checksummed does not necessarily end on a byte boundary and the crc32.. 8 bits which is immediately. Your last 32 bits is the checksum and how can that not be all zeroes I've searched google for..
