Automatic Messaging Security
PGP Desktop Home automatically encrypts, decrypts, digitally signs, and verifies email messages according to configurable policies.

Secure Instant Messaging (IM)
AIM sessions are automatically encrypted between PGP Desktop users, with no additional setup. PGP Desktop users with IM encryption are automatically identified in buddy lists. Starting a chat session begins encryption, with no extra steps needed.

Multiple Ways to Share Data
Users can create storage-independent encrypted containers for transport and sharing of specific files using PGP Self-Decrypting Archive, PGP Virtual Disk, and PGP Zip.

• PGP Self-Decrypting Archives (SDAs) - Puts files and folders into an encrypted, compressed package that can be opened on a Windows system that does not have PGP Messaging or PGP Desktop installed. SDAs are the perfect solution for securely exchanging files with someone who does not have PGP software installed.
• PGP Virtual Disk volumes - Are used just like removable disk drives or any other disk drive with encryption and decryption performed on-the-fly in the background. Virtual Disk Volumes use part of the hard drive space as an encrypted virtual disk volume with its own drive letter. A PGP Virtual Disk is the perfect place for storing sensitive files; it is as if they are stored in a safe. When the door of the safe is open (when the volume is mounted), files can be changed, taken out or moved into it. Otherwise (when the volume is unmounted), all the data on the volume is protected. PGP Virtual Disks are also self-expanding: they automatically grow to accommodate increases in data size, eliminating initial space allocation constraints.
• PGP Zip - Adds any combination of files and folders to an encrypted, compressed, portable archive. PGP Desktop must be installed on a system to create or open a PGP Zip archive. PGP Zip is a tool for securely archiving sensitive data, whether to distribute it to others or to back it up.

Secure File Deletion
PGP Shredder completely destroys files and folders so that even file recovery software cannot recover them. Deleting a file using the Windows Recycle Bin does not actually delete it; it sits on the drive and eventually gets overwritten. Until then, it is trivial for an attacker to recover that file. PGP Shredder, in contrast, immediately overwrites files multiple times. This is so effective that even sophisticated disk recovery software cannot recover these files. This feature also completely wipes free space on drives so that deleted data is truly unrecoverable.

Key Management
PGP Desktop Home automatically finds keys associated with trusted email addresses and will automatically search PGP Global Directory, a PGP service providing a single repository of current, verified keys for PGP users worldwide. Keys generated for encryption can also be optionally posted automatically to the PGP® Global Directory.
