|
<br/>
|
|
RFC4880 5.1: A Public-Key Encrypted Session Key packet holds the session key
|
|
used to encrypt a message. Zero or more Public-Key Encrypted Session Key
|
|
packets and/or Symmetric-Key Encrypted Session Key packets may precede a
|
|
Symmetrically Encrypted Data Packet, which holds an encrypted message. The
|
|
message is encrypted with the session key, and the session key is itself
|
|
encrypted and stored in the Encrypted Session Key packet(s). The
|
|
Symmetrically Encrypted Data Packet is preceded by one Public-Key Encrypted
|
|
Session Key packet for each OpenPGP key to which the message is encrypted.
|
|
The recipient of the message finds a session key that is encrypted to their
|
|
public key, decrypts the session key, and then uses the session key to
|
|
decrypt the message.</div>
