#2566 7-Zip Portable fails to encrypt

[Stephen Walker]

Portable version fails to encrypt ZIP files

Project Name: 7-Zip
Package: Core Archiving Functionality (ZIP Encryption)
Version: 24.09 (x64), portable

Operating System: Windows 10 22H2

Expected Result:
Attempting to open a 7-zip created ZIP file in Windows File Explorer should prompt the user to enter the password, since a password was given.

Actual Result:
The ZIP file opens without prompting for any password.

Steps to Reproduce:
Open 7-Zip 24.09 (x64) -- portable.
Navigate to a directory containing files to be archived.
Select one or more files.
Right-click on the selected files.
Choose '7-Zip' from the context menu.
Select 'Add to archive...'.
In the 'Add to Archive' dialog:
Set the 'Archive' field to a desired name (e.g., 'test.zip').
Set the 'Archive format' dropdown to 'zip'.
In the 'Encryption' section:
Attempt 1: Click the 'Show password' checkbox and enter a password (with spaces) in the 'Enter password' field once. Leave method as 'ZipCrypto'.
Attempt 2: Leave the 'Show password' checkbox unchecked and enter the same password (with spaces) in both the 'Enter password' and 'Re-enter password' fields. Change method to 'AES-256'.
Click the 'OK' button.
Navigate to the created ZIP file ('test.zip' or your chosen name) in File Explorer.
Double-click on the ZIP file to open it using the default ZIP handler (Windows Explorer).

See the attached test.zip file, which should have been encrypted with "This is the password."

File names are not encrypted, but data is encrypted.
