Using PGP
Prerequisites
To use PGP you will need to be in the Tandem OSS environment, to do this type osh from the TACL prompt.

In the event that the TSM client or Host Tandem are restarted, the OSS home terminal must be re-specified.  If a PGP service is to be left running, leave this telnet session running indefinitely. 

Useful commands
pgp h 			: This will initiate pgp help.
pgp kg 		: This will initiate a key pair generation
pgp kv			: displays keys held on the public key ring
pgp kx user id	: extracts public key corresponding to the selected user id
pgp kr user id	: removes public, and private keys (if you wish), from your key rings,
			: corresponding to the selected user id.
pgp ka key file	: add public keys held within the key file to your public key ring.
pgp ke user id	: edit pass-phrase for an existing key.
Note: When generating a new key pair, follow the on screen instructions, and ensure that 1024 bit encryption is used.

Implementing the use of new keys
Once a new key pair has been generated on the Tandem host (under OSS) extract the public key using the user id that was used to create it.  PGP will inform you of the name of the file that this has been extracted to, this new file needs to be sent to the directory of the PGP installation on the remote PGP machine.  On the remote PGP Host add the new public key from the new keyfile. 

Finally, ensure the sending machine uses the new user id when encrypting PGP files.
