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][1].

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.
>
