Symmetric-Key Encrypted Session-Key Packets (Tag 3)
<p>
The Symmetric-Key Encrypted Session Key packet holds the symmetric- key encryption of a session key used to encrypt a message. Zero or more Encrypted Session Key packets and/or Symmetric-Key Encrypted Session Key packets may precede a Symmetrically Encrypted Data Packet that holds an encrypted message. The message is encrypted with a session key, and the session key is itself encrypted and stored in the Encrypted Session Key packet or the Symmetric-Key Encrypted Session Key packet.
<p>
If the Symmetrically Encrypted Data Packet is preceded by one or more Symmetric-Key Encrypted Session Key packets, each specifies a passphrase that may be used to decrypt the message. This allows a message to be encrypted to a number of public keys, and also to one or more pass phrases. This packet type is new, and is not generated by PGP 2.x or PGP 5.0.
<p>
The body of this packet consists of:<ul>
<li>A one-octet version number. The only currently defined version is 4.<li>A one-octet number describing the symmetric algorithm used.<li>A string-to-key (S2K) specifier, length as defined above.<li>Optionally, the encrypted session key itself, which is decrypted with the string-to-key object. </ul>
