PGP

Setting Up a PGP Public Key on our Server:

NOTE: 'uid', 'key userid', and 'keyname' are used interchangeably.

If you do not have PGP 5.0, it can be downloaded for free at http://www.pgp.com/.

1. Create a PGP Key Pair on your hard drive.

2. Copy the public key that has been created as a text file.

3. Upload the public key text file to your home directory on the server.

4. Add the public key to your key ring on the server.

Telnet command line: /usr/local/bin/pgpk -a /home/username/filename

5. Make the public key completely trusted.

Telnet command line: /usr/local/bin/pgpk -e keyname

Choose '4' for completely trusted at all times.

6. Run a test encryption for the key from the prompt.

Create a test text file

Telnet command line: /usr/local/bin/pgpe -r key_ userid -o name_of_output_file -a name_of_text_file

Answer 'Y' when asked if trusted

7. After you are finished, you will need to contact technical support to set the permissions on your public key to be used from the web.

You now need to set up your form to use the 'pgpmail.pl':

The form action line should be:

<FORM ACTION = "/cgi-sys/pgpmail.pl" METHOD = "POST">

The 'pgpmail.pl' will do all the programming work for you. The behavior of 'pgpmail.pl' is altered by the use of hidden fields in your form.

There are three form fields that you must have in your form for PGPMail to work correctly. They are the 'recipient', 'username', and 'keyname' fields.

Field: recipient

This form field allows you to specify to whom you wish your form results to be e-mailed. You will most likely want to configure this option as a hidden form field with a value equal to that of your e-mail address.

Syntax:

<input type=hidden name="recipient" value="your_username@localnet.com">

Field: username

This field allows you to specify your username in the system. This allows PGPMail to look for the configuration files to encrypt the mail to be sent to you.

Syntax:

<input type=hidden name="username" value="your_username">

Field: keyname

This form field allows you to specify the name of your public key. This will be the public key that PGPMail uses to encrypt your mail. You must possess the private key in order to decrypt the e-mail that is sent.

Syntax:

<input type=hidden name="keyname" value="public_keyname">
