Edit report at https://bugs.php.net/bug.php?id=79634&edit=1 ID: 79634 Updated by: cmb@php.net Reported by: freshprince dot 2b at gmx dot net Summary: Could not open password protected zip archive Status: Not a bug Type: Bug Package: Zip Related Operating System: Mac PHP Version: 7.4.6 Assigned To: cmb Block user comment: N Private report: N New Comment: Oh, I just learned that classic PKWARE encryption will only be supported as of libzip 1.7.0[1], so stay tuned!

In the documentation I read "The encryption method defined by one of the ZipArchive::EM_ constants." With "EM_NONE" there is no password prompt and with "EM_AES_128", "EM_AES_192" and "EM_AES_256" the same situation will occure. ------------------------------------------------------------------------ [2020-05-26 11:22:12] cmb@php.net Thanks! That was what I expected. So this issue doesn't look to be a problem of PHP, but rather limited Zip support by the other tools you're using. Consider to file respective feature requests to the vendors of these tools, or for best portability don't use EM_AES_* encryption (but be aware that the classic Zip encryption is very weak). ------------------------------------------------------------------------ [2020-05-26 11:13:55] freshprince dot 2b at gmx dot net > I meant, please try to open the archive created by PHP with 7-zip.

A try with the 7-zip[1] was working as expected with all zip archives. Should not be there a way to create and extract a password protected zip archive, without any additional tools? Or do I understand it wrong?
