Subject: ecryptfs: unencrypted key size based on encrypted key size
From: Mike Halcrow <mhalcrow@xxxxxxxxxx>
Set the unencrypted key size based on the encrypted key size. Code to handle
the special case of AES-192; since the encrypted key size must be a multiple
of the cipher block size, we have 32 bytes of encrypted key data, and we only
take the first 24 bytes of the decrypted key data.
