for a high-compression AES 256bit encryption you can use a tar.7z. you need
to wrap the files in tar to preserve permissions and meta data and then 7z
it with AES. 7z is also a very powerfull compressor, better than zip or
gzip and can match bzip2 but be faster. you could technically use 7zip to
make AES encrypted regular zip(pkzip style) zip files.
Alternatively, you could just use tar.gz and then encrypt that file with
another program.

Don't miss this year's exciting event. There's still time to save $100.
Use priority code J8TL2D2.
