encryption/decryption on-the-fly for gvfs google drive backend

[Thomas Meyer <thomas m3y3r de>]

Hi,

would it be possible to call something like this before uploading a
file to google drive?
$ openssl enc -e -bf -pass file:/path/to/pass.txt -in "$f" -out "$f"

and when download the file from google drive:
$ openssl enc -d -bf -pass file:/path/to/pass.txt -in "$f" -out "$f"

how would I implement something like this?

any ideas?

with kind regards
thomas
