Boxcryptor Alternative, 3 Reasons to Choose BestCrypt In other words, Boxcryptor's solution is no longer available to new users, while most likely existing users will have to migrate when their contract ends. However, as of last week, it is no longer possible to create new accounts or purchase new licenses " ¹. If there is a problem, our customer support is still available. Of course it's quicker than Python (which is interpreted, not compiled).As stated on the Boxcryptor website, "Existing customers can still download Boxcryptor, for example to add a new device. ![]() But as usual, the ultimate proof of confidence would be to assess that your password is stored anywhere. That means that, without your password, nobody can decrypt your files, even them. So,what is my conclusion?Īgain I'm proud of myself: I've learned Go and this program works!īesides, I can see that Boxcryptor does what their authors says: they have implemented a zero-knowledge solution. Install Go (golang) and the requested modules So always remember your (strong) password, and keep it in a safe place (like KeePass).

Secondly, like every commercial program, you can't access the source code to audit it, and the documentation is often too incomplete for auditing purpose.Īnd, at last, in the unlikely case of the company disapear, or if the executable files are lost or too old to be used, you may want a program to decrypt your files. I wrote a Python version, then a Go version. The best way to do that is to write my own decrypting program. Why this program?īecause I'm paranoid (I'm working in a big european bank as security officer/expert), and I wanted to understand the crypto process of the Boxcryptor solution (zero-knowledge based). What is Boxcryptorīoxcryptor is a commercial software (though you can use it freely with limitations) that encrypts files in the cloud in its largest a acceptance, that means OneDrive (Microsoft), Google Drive, iCloud (Apple), ownCloud, Box, Dropbox, etc.Īll compatibles products are listed here.
