Question about use of --cipher-algo AES & --openpgp

[Werner Koch]

Hi,

While you are at it, you might want to add support for the keybox
foramt which is currently used for X.509 but will soon also store
OpenPGP keys:

  The KeyBox uses an augmented OpenPGP/X.509 key format.  This makes
  random access to a keyblock/Certificate easier and also gives the
  opportunity to store additional information (e.g. the fingerprint)
  along with the key.  All integers are stored in network byte order,
  offsets are counted from the beginning of the Blob.
  
  The first record of a plain KBX file has a special format:
  
   u32  length of the first record
   byte Blob type (1)
   byte version number (1)
   byte reserved
   byte reserved
   u32  magic 'KBXf'
   u32  reserved
   u32  file_created_at
   u32  last_maintenance_run
   u32  reserved
   u32  reserved

$ hd ~/.gnupg/pubring.kbx | head -2 
00000000  00 00 00 20 01 01 00 00  4b 42 58 66 00 00 00 00  |... ....KBXf....|
00000010  40 d6 8d 77 42 79 db 24  00 00 00 00 00 00 00 00  |@Ö.wByÛ$........|


The description should be something like 
  GnuPG keybox file version 1


Salam-Shalom,
