PGP Services integrates PGP encryption and decryption with NeXTStep through TickleServices.   There are six services provided to handle decryption, encryption, digital signature, and signature verification.  See the PGP documentation for details abot PGP.
PGP Services requires Philip Zimmermann's PGP package and Scott Hess's TickleServices.  Both are available from anonymous ftp.  To install PGP Services, copy the file PGP.ts to your ~/Library/TickleServices services directory, then Update the server from the TickleServices Front-end.
To use any of the services, select the text and choose the appropriate menu item.  If you are decrypting an incoming message in mail, it is necessary to copy the PGP message into an Edit window (unless you use the Decrypt and View option), since the decrypted message cannot be written back into the mailreader.
Most of these prompt you for your PGP passphrase.   I think the way I handle it is safe, so it is not left lying around in a variable just waiting for some other vicious service to come along and read it out.  The downfall of this is that you need to enter it everytime.  Maybe this is good, maybe this is bad.  Sounds like a question to be answered in a future release.
