Emulation
Guides on emulating older applications

PGPfreeware was Network Associates' encryption program, implementing the "Pretty Good Privacy" system for signing and encrypting text, email and data.

Other PGPfreeware versions on Macintosh Garden: PGPfreeware 6.5.1i and 6.5.2a.

Version 7.0.3 was the last freeware version to be distributed from the PGP International project, and appears to be the newest PGP implementation compatible with Mac OS 8 and 9. There are later commercial versions of PGP published by Network Associates, and the open source GPG project largely took over in the free space thereafter, though without classic Mac OS support.

Note that the installer program has a bug where it will scan all connected disks, including network and virtual volumes, so those with network discs connected should unmount them, and those in SheepShaver should turn off the file sharing function. Additionally, key generation appears to use PowerPC instructions which freeze SheepShaver, so this one has been marked as incompatible.

These were retrieved from multiple independent mirrors of PGP Inc.'s long-defunct FTP. There's plenty of reason to distrust these sources, however, all duplicate versions proved identical. That said, as obsolete cryptography abandonware you should understand that it is very likely not worthy of your trust!

The downloads include a signature within their respective self-extracted folders.

A trimmed down version of Network Associates' description of PGP from the included PGP User's Guide, and the feature list for this version from the Read Me file, follow:

About PGP

PGP is part of your organization’s security toolkit for protecting one of your most important assets: information. Corporations have traditionally put locks on their doors and file cabinets and require employees to show identification to prove that they are permitted access into various parts of the business site. PGP is a valuable tool to help you protect the security and integrity of your organization’s data and messages. Formany companies, loss of confidentiality means loss of business.
This guide describes how to use PGP® Freeware for the Macintosh. PGP Freeware (also referred to in this document simply as PGP) has many new features, which are described in the ReadMe.txt file that accompanies the product.

New Features in PGPfreeware 7.0.3

VPN

  • Next generation client-to-client VPNs. PGP 7.0 includes revolutionary peer-to-peer VPN capabilities that enable truly scalable network encryption. If enabled, PGP 7.0 will attempt to communicate via IPsec whenever an IP-based connection is attempted to or from another network device. This behavior can be controlled and can be enabled only in environments that require this level of security.
  • Optimized VPN connection performance via new MTU path discovery capability. PGP now automatically determines the optimal packet size (MTU, Maximum Transmission Unit) for each VPN connection. This eliminates any packet fragmentation that may occur due to intermediate Internet routers that use smaller packet sizes than the users ISP or your corporate network.

PGP Key and X.509 Certificate Support

  • New RSA key format. PGP 7.0 introduces a new RSA key format that provides support for PGP's designated revoker, multiple encryption subkeys and photo ID features. Previously these features were only available to users with Diffie-Hellman keys. PGP will continue to support users who have RSA keys in the older key format (now called the RSA Legacy key format).
  • Support for using X.509 certificates for secure email. This release gives users the choice of what type of keys/certificates to use for exchanging secure email (e.g., PGP keys and/or X.509 certificates). PGP 7.0 users can also concurrently send an encrypted email to users with PGP keys as well as other users with X.509 certificates.
  • Automatic X.509 certificate lookup from LDAP directories. If the X.509 certificate of a secure email recipient is not cached locally on the senders PC, PGP can now automatically search a pre-defined list of LDAP directories for that user's certificate. Users can also use the PGPkeys application to perform manual searches of LDAP directories for X.509 certificates.
  • Support for storing and searching for PGP keys on LDAP servers. Extending support for storing PGP keys on servers other than PGP Certificate Servers and PGP Keyservers, PGP can now store and retrieve PGP keys from any standard LDAP v2 or v3 compliant directory.
  • PGPkeys is able to open to multiple keyrings at once. Users can now open and manage multiple keyrings at a time, thus simplifying keyring management.
  • A new automatic backup feature allows the user to automatically back up keyrings to the keyring directory or another directory when any changes are made to the keyring. PGP no longer creates a series of backups in the keyring folder. Automated keyring backup is now entirely in the user's control.

Entropy and Cryptographic Algorithms

  • Continuous entropy collection. PGP now continuously collects random data from mouse movements and keystrokes (whether a PGP-related window is open or not), and stirs that random data into the PGP entropy pool.
  • Twofish support. PGP introduces the option of encrypting email, and files using Twofish, a relatively new, but well regarded 256-bit cipher. Twofish is one of five finalists for NIST's new Advanced Encryption Standard (AES).

Single Sign On

  • Improved overall ease-of-use via new centralized passphrase caching. PGP 7.0 simplifies users lives by only requiring them to enter their passphrase once to one of the many PGP components, and then the user can launch any of the other PGP modules without needing to enter their passphrase again (unless configured to do so by the administrator).

Screen Locking

  • PGP now supports screen locking on demand and after a specified delay. When your screen is locked, all cached passphrases are automatically cleared. The screen locking is immune to debuggers and other system utilities. The only ways to bypass the screen locking are to enter your passphrase (after hitting Escape), or force a reboot – in which case your PGPdisks are of course no longer mounted.

As an addendum: I have scanned these archives and their contents using VirusBarrier 1.6.2 (with definitions from 2002, which I believe is the most modern possible scanner for OS 9) and they came up clean!
