PGP Corporation Encryption Applications
- This section describes commercial programs available from PGP Corporation. For information on other programs compatible with the OpenPGP specification, see External links below.
While originally used primarily for encrypting the contents of e-mail messages and attachments from a desktop client, PGP products have been diversified since 2002 into a set of encryption applications which can be managed by an optional central policy server. PGP encryption applications include e-mail and attachments, digital signatures, laptop full disk encryption, file and folder security, protection for IM sessions, batch file transfer encryption, and protection for files and folders stored on network servers and, more recently, encrypted and/or signed HTTP request/responses by means of a client side (Enigform) and a server side (mod openpgp) module. There is also a Wordpress plugin available, called wp-enigform-authentication, that takes advantage of the session management features of Enigform with mod_openpgp.
The PGP Desktop 9.x family includes PGP Desktop Email, PGP Whole Disk Encryption, and PGP NetShare. Additionally, a number of Desktop bundles are also available. Depending on application, the products feature desktop e-mail, digital signatures, IM security, whole disk encryption, file and folder security, self decrypting archives, and secure shredding of deleted files. Capabilities are licensed in different ways depending on features required.
The PGP Universal Server 2.x management console handles centralized deployment, security policy, policy enforcement, key management, and reporting. It is used for automated e-mail encryption in the gateway and manages PGP Desktop 9.x clients. In addition to its local keyserver, PGP Universal Server works with the PGP public keyserver—called the PGP Global Directory—to find recipient keys. It has the capability of delivering e-mail securely when no recipient key is found via a secure HTTPS browser session.
With PGP Desktop 9.x managed by PGP Universal Server 2.x, first released in 2005, all PGP encryption applications are based on a new proxy-based architecture. These newer versions of PGP software eliminate the use of e-mail plug-ins and insulate the user from changes to other desktop applications. All desktop and server operations are now based on security policies and operate in an automated fashion. The PGP Universal server automates the creation, management, and expiration of keys, sharing these keys among all PGP encryption applications.
The current shipping versions are PGP Desktop 10.2.0 (Windows and Mac-OS Platforms) and PGP Universal 3.2.0.
Also available are PGP Command Line, which enables command line-based encryption and signing of information for storage, transfer, and backup, as well as the PGP Support Package for BlackBerry which enables RIM BlackBerry devices to enjoy sender-to-recipient messaging encryption.
New versions of PGP applications use both OpenPGP and the S/MIME, allowing communications with any user of a NIST specified standard.

Famous quotes containing the word corporation:
“What I am anxious to do is to get the best bill possible with the least amount of friction.... I wish to avoid [splitting our party]. I shall do all in my power to retain the corporation tax as it is now and also force a reduction of the [tariff] schedules. It is only when all other efforts fail that I’ll resort to headlines and force the people into this fight.”
—William Howard Taft (1857–1930)
