If git-annex stores the decrypted symmetric cipher in memory, then there
is a risk that it could be intercepted from there by an attacker. Gpg

amelorates these type of risks by using locked memory. For git-annex, note
that an attacker with local machine access can tell at least all the
filenames and metadata of files stored in the encrypted remote anyway,
and can access whatever content is stored locally.
This design does not support obfuscating the size of files by chunking
them, as that would have added a lot of complexity, for dubious benefits.
