Extending support for storing PGP keys on servers, other PGP Certificate Servers, and PGP Keyservers. PGP can now store and retrieve PGP keys from any standard LDAP v2 or v3 compliant directory. Silent keyring maintenance. PGP now performs automatic, unattended keyring maintenance such as key synchronization, trusted introducer updates, CRL downloading, etc. without displaying any non-critical dialog boxes. 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. Continuous entropy collection. PGP introduces the option of encrypting email, files and ICQ instant messages using Twofish, a relatively new, but well regarded 256-bit cipher.
