Re: encfs Filenames
Knowing the plaintext and encrypted result does not impact the effectiveness of the encryption much. Even if an attacker knows the original plaintext and the encrypted file, he has no way of knowing the original key used. Of course, knowing the plaintext DOES defeat encryption for that file, obviously.
Also, how would knowing the filenames allow someone to get the encryption key? He may be able to infer what is contained in the file, but couldn't know for sure.
If you are planning on encrypting a partition, I suggest you instead use LUKS or TrueCrypt. Those two encrypt everything, including the filenames.
The whole thing is so patently infantile, so foreign to reality, that to anyone with a friendly attitude to humanity it is painful to think that the great majority of mortals will never be able to rise above this view of life.
