GnuPG can be used for symetrical ciphering only. Excerpt from gpg
manpage :

~$ man gpg
[...]
       -c, --symmetric
                 Encrypt with a symmetric cipher using a passphrase. The
                 default symmetric cipher used is CAST5, but may be
                 chosen with the --cipher-algo option.

So :

	gpg -c --cipher-algo 3DES test.txt
	gpg -c --cipher-algo AES256 test.txt

Will give test.txt.gpg output (can be changed using -o/--output).
