Using 7-Zip on Windows to create an encrypted container.
7-Zip can be installed on your University supported Windows desktop via the Software Center. Alternatively, if you are on a self managed machine, it can be downloaded from the manufacturer's website.
Right-click on the file or folder you want to add to an encrypted archive. Select 7-Zip, then Add to archive…
Change the Encryption method to AES-256.
Click OK.
The encrypted zip archive file will be created in the same location as the original file or folder. It can now be sent securely via email as an attachment.
Use a medium other than email to transmit the password to the intended recipient - ideally phone or face-to-face.
Right-click on the zip archive. (Note: If you received the zip file as an attachment, save this to a folder first, then right-click the file.)
Select 7-Zip, then Extract files…
Select the destination for the extracted files. Enter the password.
Click Ok. Your files will be decrypted and extracted to the location you previously specified.
