NEW FEATURES

1. Expanded X.509 certificate support. X.509 certificate requests can be created for existing PGP keys. Additionally, existing X.509 certificates can be imported onto a PGP key ring. The PGPsdk recognizes X.509 certificate revocation lists (CRLs) and incorporates the revoked certificate information therein into validity calculations for imported X.509 certificates.
2. X.509 Certificate Authority (CA) support. The PGPsdk supports performing online certificate requests and retrievals, CRL retrievals from Network Associates Net Tools PKI 1.0, VeriSign OnSite PKI 4.0, and Entrust PKI 4.0 (using the Entrust VPN Connector 4.1).
3. X.509 TLS support. X.509 certificates and certificate chains can now be used to authenticate a PGP Transport Layer Security (TLS) session.
4. X.509 private key import. X.509 private keys created with other products (e.g., web browsers, etc.) can now be imported into a PGP keyring using the PKCS #8 or #12 interchange formats.
5. Low-level session key support. The session key used to encrypt a PGP message can now be retrieved during encryption and a message can be explicitly encrypted using a given session key. This feature allows for decrypting a specific message without explicit knowledge of the passphrase for the private key if the session key for the message is known.
6. Random pool security enhancement. Additions to the random pool are bufferred internally to impede state-following attacks.
7. Miscellaneous.
   - DSS key sizes are now forced to be multiple of 64 bits as required by the standard.
   - The internal limit on the number of outstanding key sets have been increased approximately five fold.
