Exploitability: Low
Security Impact: Low

EncFS uses the same key for encrypting data and computing MACs. This is generally considered to be bad practice.

EncFS should use separate keys for encrypting data and computing MACs.

Remove EncFS

From the latest audit (https://defuse.ca/audits/encfs.htm):

> EncFS is probably safe as long as the adversary only gets one copy of
> the ciphertext and nothing more. EncFS is not safe if the adversary has
> the opportunity to see two or more snapshots of the ciphertext at
> different times. EncFS attempts to protect files from malicious
> modification, but there are serious problems with this feature.
