Secure Email (PGP)

To send me a secure strongly encrypted message, you will need a copy of the PGP software available free from http://www.pgp.com. The Gnu open source package GPG comes as a standard pre-installation with many operating system distri­butions. With suitable PGP software installed on your computer, please proceed as follows:

Download and Import my Public Key

1. Please right-click on this link and select the option to save the file rjmpubkey.pgp in your home directory.
2. Open a terminal window.
3. Copy and paste the following command into the terminal:

   gpg --import rjmpubkey.pgp

4. Press the RETURN key.
5. You can now delete the downloaded file or save it somewhere.

Write, Encrypt and Send Your Message

1. Write your message to me in a file (e.g. yourmessage.txt).
2. Open a terminal window.
3. Go to (cd) the directory containing your message file.
4. Copy and paste the following command into the terminal:

   gpg -o yourmessage.pgp -e -r rjmpubkey yourmessage.txt

5. Press the RETURN key.
6. Copy and paste the contents of yourmessage.pgp into my email form or into a normal email sent to my email address shown in the coloured illustration on the previous page.

NOTE: sending the message as an attachment rather than as an encrypted email is more secure and avoids compatibility problems between different proprietory email clients.
