Session key is a key used to actually encrypt the message in GnuPG using a
symmetric crypto algorithm (e.g. AES256) and then the key itself is encrypted
using the public key of the recepient. A new session key is generated for each
message/file.

I got confused about the error output from duply/duplicity and some of the
comments in duply's config files and thought that the passphrase being asked
is actually used as the session key, but as far as I can tell, there's no way
to specify a session key when encrypting with GnuPG - it is always generated.

Don't mind me :)
