Hi, thanks for your quick reply! I am in testing, and I installed the sid version to confirm if the bug is there too.
I follow your steps and I confirm it works as expected. You can see here the reproducible steps (using the password 1234): $ echo bar > bar $ echo baz > baz $ 7z a -mem=AES128 -tzip -p1234 foo.zip bar baz 7-Zip 24.09 (x64) : Copyright (c) 1999-2024 Igor Pavlov : 2024-11-29 64-bit locale=C.UTF-8 Threads:4 OPEN_MAX:1024 Scanning the drive: 2 files, 8 bytes (1 KiB) Creating archive: foo.zip Add new data to archive: 2 files, 8 bytes (1 KiB) Files read from disk: 2 Archive size: 350 bytes (1 KiB) Everything is Ok $ mkdir test && cd test $ unar ../foo.zip ../foo.zip: Zip bar (4 B)... This archive requires a password to unpack. Password (will not be shown): Failed! (Missing or wrong password) baz (4 B)... Failed! (Missing or wrong password) Extraction to directory "foo" failed (2 files failed.) as you can see, the problem is with .zip files created with 7z and -mem=AES128
