Function open() return wrong status

[Yuea922]

zlib-1.3 + quazip-1.4 + qt-5.14.1

When I open an encrypted archive, the open() function always returns true
When the password is correct, readall() can read the data normally.
When the password is wrong, the size of the decompressed files will be 0Kb
The compressed package is generated using 7-zip and encrypted using the zipcrypto algorithm.
How should I decompress the encrypted compressed package?
Looking forward to your answer
Thank you
