file-encryption

I want to acomplish something rather simple (at least it would seem to be):

Compress a directory
Encrypt the compressed file
Upload the compressed & encrypted file via FTP

I also want to acomplish this in an automated fashion on Linux server.

TrueCrypt is not really an option as it seems it can't complress a single file, instead you have to make a volume that you mount and move the files into.

This question answers how to do the the upload and I know how to compress a directory. It is just the encryption that's giving me problems.
