Sending me encrypted stuff

You can use my key to send me encrypted messages and files even if you don't have your own key. Assume you want to send me something called file.txt (it can be any file, including binary ones). From the command line, do the following:

First, fetch the key from the key server.

gpg --recv-keys --keyserver pool.sks-keyservers.net E88432C3

Then, encrypt file.txt to a new, encrypted, file with 'ASCII armour' (ie binary-to-text encoding).

gpg --output file.gpg --encrypt --armor --recipient E88432C3 file.txt

Then just send me the the resulting file file.gpg.
