.zip 压缩是否在内部维护校验和? [英] Does .zip compression internally maintain a checksum?

问题描述

.zip 存档是否在内部维护其中文件的校验和?

Does a .zip archive internally maintain a checksum for the files in it?

如果它维护一个校验和，我如何确保在解压过程中校验和得到验证?以及是否可以不解压验证校验和?

If it maintains a checksum, how can I be sure the checksum is verified during decompression? And is it possible to verify the checksum without decompressing?

推荐答案

是的，zip 为存档中的每个文件保存了 CRC-32 校验和，它应该在解压过程中进行验证.

Yes, zip holds CRC-32 checksum for each file in archive, and it should verify it during the decompression.
