eCryptfs files will have similiar looking headers because the follow the
same format. The "_CONSOLE" string is part of the spec (the exact format
eludes me right now), so that is nothing to worry about. As for file size,
eCryptfs encrypts whole pages and introduces a header page, so your files
should always be slightly larger (minimum of 1 page) than the non-cipher
version of the file.

Yup, these sequences are just the standard eCryptfs headers that are
placed in every file encrypted by eCryptfs.
