Answer 2

In order to archive a directory into an encrypted package.

Combine tar, gzip and gpg. You will need the GnuWin32 utils installed, as well as GnuPG.

tar czf archive.tar.gz mydirectory/  # => archive.tar.gz 
gpg -c archive.tar.gz                # Input password. => archive.tar.gz.gpg
rm -rf mydirectory archive.tar.gz    # remove the plaintext residue.

gpg -c is symmetric encryption.
