![]() A file manager like ES File Explorer can create/extract password protected ZIP files on a Chromebook that supports Android Apps.* RSS Readers – With all the problems associated with getting news from social media, old-school RSS aggregators are making a comeback. No one can open your files unless they have your cloud credentials AND zip password. I do this for my cloud backups (using a different program in Windows). most modern operating systems support unzipping a password protected zip even if they don't natively support adding the password to begin with. If you use a strong password, password protected zip files offer very strong level of encryption and are broadly portable (note the current version of the MLP app uses AES-256). You can 'zip' files on a Chromebook by just right-clicking on a file or folder in the 'Files' app and choosing 'ZIP selection', then open the "My Little Password" app to password protect the zip file. Not the most professional looking, as it's decorated with 'My Little Pony' characters. There is a Chrome app called "My Little Password" How else would the data be written to the Google drive? There is an excellent security white paper available on their site that will answer your questions. The Google credentials are needed to write the encrypted blobs. It can't be a randomly generated key that's just stored on your computer as you would need this key to recover your data if your device were stolen. If it's a randomly generated key that Boxcryptor is storing for you then they both have the key and access to your Google credentials, which is equivalent to having access to your files. If the encryption is done on your own machine why do they need your Google credentials at all? Also what key is being used to encrypt the files? If it's one derived from a password then this isn't any better than just using freely available software (e.g. One needs to look carefully at these technologies to understand whether "they'll still potentially have access to your files". Boxcrypytor has zero knowledge encryption which means the encryption is done on your local machine and only you know the passphrase. Google would have "access" to encrypted files. If you don't trust Google to access your files why do you trust another third party? But they'll still potentially have access to your files. ![]() Why would Boxcrypytor have access to your email if you use a different Google account? Your email has so much personal information.Boxcrypytor doesn't need to be malicious to make basic mistakes. This actually opens bigger attack vectors than just encrypting nothing at all. You shouldn't share passwords with third parties. It also ran fine on 2010 hardware, but video streaming (netflix) crashed sometimes. I have no problem with Lubuntu on 2013 hardware, it still flies. Linux is like a more expanded chromebook, and will run on very similarly poor/underpowered hardware. You will need Linux, Windows, or Mac, though, chromebook won't do it, I do not think. If you want a GUI, after you set up the rclone config, you can download rclonebrowser, which will let you do all the copy/restore/etc graphically. I was able to backup and restore just fine, no issues, and everything is encrypted and speedy. Here's a tutorial (read through until they do the first "copy", then skip down to the "encryption" section, since that's what you want). I ended up using rclone on top of gdrive, and it was a bit messy, but if you can figure out something like rsync that it should be no trouble. I do not think you will be able to successfully do encryption in the cloud in the way you want with only a Chromebook. I also did some full encrypted backups with Duplicati, and when I went to try a restore everything went to hell (was never able to successfully restore a file back from the encrypted cloud backup on gdrive). I had only bad experiences with Boxcryptor (totally unreliable, cancelled/failed uploads, partial files left all over the place) and Cryptomator (same sort of thing).
