Ugh. This “zero knowledge encryption” is NOT zpf. Just a per user PBE hiding a shared symmetric key.
I kept reading, trying to find the innovative way of encrypting large amount of data while not revealing the same key to all participant - some SSS variant or fast FHE or maybe a cool new PRE.
Also, all value added features besides shipping the bytes are gone when something like this is in effect. Search, preview, co-edit, metadata extraction.
I guess I’m disappointed / venting because of crushed hopes. I’m in this field and hoped something new and exciting is starting. Not trying to criticize the engineering work, which looks quite well done, just sad there isn’t new algorithmic development.
- sillysaurusx 4y agoYou didn’t explain what the right answer is.
- bironran 4y agoOf course I didn’t. As I said, I was hoping for a new development.
- fullsend 4y agoWhat do you mean SSS, FHE, PRE? What would you like to see?

- bironran 4y agoPRE - proxy (blind) re-encryption. All of these are true “zero knowledge” methods that don’t require the encryption key to be shared, and therefore be granted irrevocably.
- TJSomething 4y agoBoxcryptor was originally just a wrapper around Encfs and a Dropbox API client and probably hasn't significantly changed how they worked since they made it a fancy service. I assume that they rebuilt something like Encfs, but closed source.
