Box's greatest problem is that they don't encrypt on your device. This means their server decrypts everything before it stores and reencrypts it.

This way, if someone gains access to their servers (like the NSA or a hacker), the intruder can read your data as well. At Tresorit, we use client-side encryption so noone,…

Yep, we haven't been hacked for 3 months and counting. :)

Alan, deduplication is made possible by Bitcasa using 'convergent cryptography'. That basically means if you encrypt file A and I encrypt file A, the resulting encrypted data is the same. The file's 'hash' is used as the encryption key, and a hash is generated from the file itself.
