For backwards compatibility, it can extract old images created with the original ImPack.<br /> <br /> Data can be encrypted ([[AES]], Camellia, Serpent, Twofish) and/or compressed (Deflate, [[Zstd]], [[LZMA2]], [[Bzip2]], [[Brotli]]) before being stored inside the image. Additionally, ImPack2 includes the original filename for convenience and a CRC checksum to verify the data's integrity.<br /> <br /> <br /> <br /> == Links ==<br /> * [https://github.com/Jannis234/ImPack2 ImPack2]<br /> * [https://sourceforge.net/projects/jm-impack/ ImPack]<br /> * [https://github.com/Jannis234/ImPack2/blob/master/doc/image-format-spec.txt Image format specification]</div>
