The following command:
gpg --s2k-digest-algo SHA256 --s2k-cipher-algo AES256 -c myfile
is used to create a symmetrically encrypted file.
The output, however, seems to utilize old OpenPGP format packets. For example,
gpg --list-packets --verbose myfile.gpg
#off=0 ctb=8c tag=3 hlen=2 plen=13
:symkey enc packet: version 4, cipher 9, s2k 3, hash 8
salt 367FDD829963CC11, count 4194304 (192)
which, to my understanding, denotes an old format packet (ctb=8c, not cc)
I cannot locate a configuration option which might be causing the old OpenPGP format to be used. I also can't find a setting which might enable use of the new OpenPGP format.
Is this behavior as expected?
