Boxcryptor crashing on Android for other than AES-256

pongnguy

I recently changed my encryption and block size to something lower than AES-256 and 4096, respectively. I noticed that it causes the Boxcryptor Android app to crash. The problem went away when I changed the encryption back to AES-256 and block size of 4096. I decreased my block size to improve performance when reading many small files.

Hello pongnguy

thank you for your feedback! This issue is currently on our Android ToDo list and we will fix it as soon as possible. As it has a low priority (because in general we don't recommend to change these settings) I can't say when we will release this fix.

Best regards

Yes, I've also noticed that both iOS and Android fail to correctly decrypt AES-128. And by fail, I mean crash on Android and incorrectly sending bad (incorrectly decrypted files) on iOS.

Boris' response seemed to indicate that this is a feature that hasn't been implemented, but the correct use of software that causes the software to crash is still a bug. At the very least, the software should fail gracefully, indicating that it cannot decrypt files from the desktop version of boxcryptor (which is NOT what the marketing info says, btw).

I was hoping to select the level of encryption depending on the type of data. Now I'm forced to decrypt and re-encrypt 100+GB of data so that it will work on iOS, Android, and PC. Sigh. :)
