[NCLUG] Ubuntu 8.04 - file encryption

[Rob Bayerl]

It seems to me that is simply a GUI for gnupg. I only have Ubuntu
installed in a virtual machine and didn't play with it too much (I
don't even have a gpg key on there) but the command line equivalent
would be something like:

gpg -ser <your name> file_to_encrypt

where your name would most likely be your e-mail address (you can
specify multiple recipients with multiple -r switches: '-r <name>').
This will create a file_to_encrypt.gpg which contains the encrypted
data. If you want it to use only ASCII, use -sear...which will create
file_to_encrypt.asc.

You can then decrypt it with gpg -d file_to_decrypt.gpg

Note that this method also includes your digital signature (the -s switch).
