Encryting both file contents and file name with GnuPG

[Neil Phillips]

Hi,
I'm completely new to GnuPG.
Can someone tell me how I can encrypt the name of the file that I want to
encrypt please.

Example:
mySecrets.txt [a plain text file]

I would like:
szstt.asd [some 'apparently random name' file] [file contents encrypted]

I see that secureZip can do this, I have used a trial version with success.

However I would prefer to use GnuPG if possible.

Neil
