You can do without saving temp unencrypted files:
tar cf - /data/* | pbzip2 -9 | openssl ....
(choose openssl parameters from ohers' posts)
Restore:
openssl -d ... | bzcat | tar tvf -
tar cf - /data/* | pbzip2 -9 | openssl ....
(choose openssl parameters from ohers' posts)
Restore:
openssl -d ... | bzcat | tar tvf -
don't use the built in zip - the encryption is of low quality and easily bypassed.
openssl or gpg are good choices, but don't compress and should be used to encrypt a tgz after the fact. Versions are of course available to decrypt on windows.
7z is available for linux, can compress well, and encrypt with AES@256 bit. In ubuntu (at least) you can install by typing "apt-get install p7zip-full"
command then is "7z a -p<password> <archive>.7z <filespec>"

I prefer tar and gpg.
This command will tar up the files, and compress with gzip, then encrypt with gpg.
tar czvpf - file1.sql file2.txt | gpg --symmetric --cipher-algo aes256 -o myarchive.tar.gz.gpg
it will ask you from a passphrase that you will need to decrypt later.
To decrypt and extract you would run:
gpg -d myarchive.tar.gz.gpg | tar xzvf -
