_level is not used in decode. But I think _ver_major and _ver_minoris needed. The version can determine whether decompression is supported

AES encryption 7-Zip supports encryption with the AES-256 algorithm. This algorithm uses a cipher key with length of 256 bits. To create the key, 7-Zip uses a derivation function based on an SHA-256 hash algorithm. A key derivation function produces a derived key from a text password defined by the user. To increase the cost of an exhaustive search for passwords, 7-Zip uses a big number of iterations to produce the cipher key from the text password. Tips for selecting password length Here is an estimate...

I maintain a fork version of p7zip on github. https://github.com/jinfeihan57/p7zip Many people in the community are very interested in p7zip. I believe once the source code of 7zip-21.0 is released, and the community will definitely help complete the 7zz Linux build script as soon as possible. https://github.com/jinfeihan57/p7zip/issues/114

Can 7zip make XZ format with CRC64 ? If YES, How? Thanks.

On windows try this https://github.com/mcmilk/7-Zip-zstd

I fixed tar link file decompress as regular file. OR you can download https://github.com/szcnick/p7zip the dev branch.

I tested that tarfile cannot be decompressed correctly, but zipfile can be decompressed correctly. Am i right？

I ca n’t refute you, I will update the real new version, but it will take time, but the CVE bug is more urgent, so I released a version to fix the bug, and some other updates that will not cause bugs will be updated later.
