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
7.0.3][1].
Due to [legal issues in the 1990s][2], PGP tools were released in two
versions; PGP America and PGP International. Before the year 2000 it
was illegal to export PGP America to other countries (except Canada!)
as the program's encryption is considered munitions by the U.S.
government's export controls. Likewise, the International version was
illegal to use within the USA, as it implemented an algorithm for
which a U.S. corporation held a patent. Meanwhile, it was a
requirement that source code for the export version be published along
with binaries, so source is available for the International but not
U.S. version.
As time has now passed and the export restrictions are relaxed, the
original export controls no longer apply, and both versions are
therefore included in this listing for posterity;
* `PGPfreeware652a.sit.hqx` is the last known American version of
the 6.5 series, version 6.5.2a.
* `PGP651IntFreeware.hqx` is the last known International version of
the 6.5 series, version 6.5.1i.
It's also worth noting that the installer programs have a bug where
they 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.
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.
Additionally, PGP signatures were provided for the International
versions, which matched the below signature (originally provided
alongside the hqx file in a file called `PGP651IntFreeware.hqx.sig`,
but this extension is not permitted on Macintosh Garden), which
appears to stem from one of the real authors of the distribution. All
that said, as obsolete cryptography abandonware you should understand
that it is very likely not worthy of your trust!

Additionally the source code associated with version 6.5.1i, retrieved
from another third party mirror, is signed with this signature:

The American version does not include a signature for the outer
`sit.hqx` file, but both versions include a signature within their
respective self-extracted folders, which both appear to check out.
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. For many companies, loss of
> confidentiality means loss of business.
> Entire books have been written on the subject of implementing
> network security. The focus of this guide is on implementing PGP as
> a tool within your overall network security structure. PGP is merely
> one piece of an overall security system, but it is an extremely
> important one. PGP provides encryption, which protects data from the
> eyes of anyone for whom it was not intended, even those who can see
> the encrypted data. This protects information from both internal and
> external ?outsiders.?
>
> ## New Features in 6.5.1
>
> * PGPnet. PGPnet is a landmark product in the history of PGP.
> PGPnet secures all TCP/IP communications between itself and any
> other machine running PGPnet. It is also fully interoperable with
> the Gauntlet GVPN firewall/gateway providing a complete solution for
> corporate remote access VPNs using the industry standard IPSec
> (Internet Protocol Security) and IKE (Internet Key Exchange)
> protocols. PGPnet has also been successfully tested with Cisco
> routers (requires Cisco IOS 12.0(5) or later with IPSec TripleDES
> Feature Pack), Linux FreeS/WAN, and many others. PGPnet is also the
> first IPSec product to fully support the use of OpenPGP keys for
> authentication in addition to X.509.
> * Self-Decrypting Archives. You may now encrypt files or folders
> into Self-Decrypting Archives (SDA) which can be sent to users who
> do not even have PGP. The archives are completely independent of any
> application, compressed and protected by PGP's strong cryptography.
> Using this feature without a passphrase will also allow you to
> create compact Self-Extracting Archives (SEA) which are not
> encrypted. The resulting archives run on both PowerPC and 68K Macs,
> and are encrypted using CAST.
> * Automated Freespace Wiping. PGP's Freespace Wipe feature now
> allows you to use AppleScript to automate wiping of the freespace on
> your disks. The AppleScript dictionary for this is located in
> PGPtools.
> * PGPmenu Improvements. PGPmenu has been entirely rewritten, and
> sports many new features. Configurable Command Key support allows
> you to invoke the Encrypt/Sign/Encrypt&Sign/Decrypt&Verify commands
> in third-party applications without even touching the mouse. The
> Empty Trash command in the Finder can now be turned into a Wipe
> Trash command to make sure that everything you throw away gets
> securely wiped. The cursor now provides animated progress during
> PGPmenu operations, and more.
> * Outlook Express support and Enhanced Email Integration. As part
> of the new PGPmenu, Outlook Express and Claris Emailer are now
> recognized as special applications in which PGPmenu will
> automatically grab the recipient email addresses whenever you invoke
> PGPmenu on a new email message window thus cutting out the step of
> specifying the recipient keys! The old Claris Emailer plugin has
> been removed now that PGPmenu has direct support for it.
> * Fingerprint Word List. When verifying a PGP public key
> fingerprint, you can now choose to view the fingerprint as a word
> list instead of hexadecimal characters. The word list in the
> fingerprint text box is made up of special authentication words that
> PGP uses and are carefully selected to be phonetically distinct and
> easy to understand without phonetic ambiguity.
> * HTTP Proxy Support. If your Macintosh is behind a corporate
> firewall with an HTTP proxy server, PGP now supports accessing HTTP
> keyservers through the proxy. To use this feature, you must
> configure the proxy server address in the Internet control panel.
> This feature requires the installation of Internet Config for users
> not running MacOS 8.5 or greater.
> * Smart Word Wrapping. The word wrapping in PGP now automatically
> rewraps paragraphs and even quoted paragraphs resulting in much
> cleaner signed messages.
>
>
> ## PGP Version 6.5.2a Enhancements
>
> * MacOS 9 Compatibility. PGP 6.5.2a provides compatibility with
> MacOS 9's Multiple Users feature.
> * Windows 2000 IPSec Interoperability. PGPnet can now establish
> VPN connections with properly configured Windows 2000 systems
> running the Microsoft High Encryption Pack.
> * HFS+ FreeSpace Wiping on Startup Volume. PGPtools now supports
> freespace wiping of HFS+ startup volumes.
> * Outlook Express 5.0 Support. In addition to our previous support
> for OE 4.5, PGP 6.5.2a now includes integrated support for the new
> Outlook Express 5.0!
>
