With mailbox.org Guard, it is now also possible to encrypt and decrypt files on your cloud storage (Drive). Similar to how it works with your e-mails, Guard will use your public and private PGP keys to perform these tasks. You may choose the menu entry New -> Add and encrypt local file in Drive.
When looking at your online folders and files, you can identify the encrypted files by a little padlock symbol displayed next to their file icon.
To open an encrypted file, select the file and click on view icon – you will then need to enter your Guard password to proceed. For convenience, you may tell the browser to remember your password for a limited time in order to avoid having to enter it frequently.
You can view file only up to 5 MB.
Downloading encrypted files
You can download your encrypted files from the Drive directly, without having to decode them first. Left-click on Download, an the file will be retrieved in its encrypted form.
If you wanted to download the file in unencrypted form, you have to remove encryption first. Open the context menu of the file and the option to remove encryption. Afterwards you can download the file in unencrypted form.
