Guide to Secure Email with PGP/GPG

If you want to send a message by email but would prefer not to pass it over the internet without encryption then read on. Two methods are described, using the original PGP and the GPL'd Gnu Privacy Guard (GnuPG).

Using GnuPG:

Alternatively you can use The Gnu Privacy Guard GnuPG. GnuPG is a complete and free replacement for PGP. Because it does not use IDEA or RSA it can be used without any restrictions. To use this system you need to:

Download and install a copy of GnuPG
Prepare your message as a text file.
Download my Public Key, or copy the above and paste into a file.
Add my key to your 'keyring' with the command:
```
gpg --import nscpub.asc
```
Encrypt the file for email transmission: eg.
```
gpg -e -r nsc message.txt
```
Send the encrypted ascii file 'message.txt.gpg' in an email to the recipient.

If you use Pine, you may want to try PGP4Pine which makes use of GPG simplicity itself.

Using PGP:

You can encrypt your message using PGP. This is a public key encryption system from Pretty Good Software and is available in the public domain. To use this system you need to:

Download and install a copy of PGP
Prepare your message as a text file.
Download my Public Key, or copy the above and paste into a file.
Add my key to your 'keyring' with the command:
```
pgp -ka nscpub.asc
```
Encrypt the file for email transmission: eg.
```
pgp -e -a message.txt nscpub
```
Send the encrypted ascii file 'message.asc' in an email to the recipient.
