Decrypting a password protected zipfile

On windows, you will need a zip program that supports password-protected (encrypted) zipfiles.

We recommend using 7zip, which should be installed on your Windows computer. Otherwise, 7zip can be downloaded from here:

Download and install the appropriate edition.

Right click on the zipfile you've received, go to 7-Zip, click "Extract to (name of file)...".  It will prompt you for the password, enter it, and the zip should be extracted.

On Macs, you will need Keka, obtainable here:

After downloading and installing Keka, you can simply drag the zipfile to the Keka icon.  A password prompt will appear, enter in the password, and the zipfile will be extracted to its original location (where you dragged it from).
