Dear GNUPG developers.

  I want to the file that must use *both* two keys. Is there any way to
do so that already exists?
  If no, I'm try to extend PGP format like under.

*Public Key Encrypted Session Key Packet for decrypting.
*Symmetric-Key Encrypted Session Key Packet for decrypting "Packet in
*Encrypted Data that contain session key for main Encrypted Data.
  |(Pakcet In Packet)
  | *Public Key Encrypted Session Key Packet
  | *Symmetric Encrypted Data Packet for decrypting main "Encrypted Data
*Main Encrypted Data.

If you find problem about this format any suggestion, please teach.

Thank you.
