KEYMAN Security key and certificate management

Syntax Development Group (SDG)

KEYMAN is a message providing for security key and certificate management. A key may be a secret key used with symmetric algorithms, or a public or private key used with asymmetric algorithms.

   To head, identify and specify a message.

   1. Data element S009/0057 is retained for upward compatibility. The use of
   S016 and/or S017 is encouraged in preference.
   2. The combination of the values carried in data elements 0062 and S009 shall
   be used to identify uniquely the message within its group (if used) or if
   not used, within its interchange, for the purpose of acknowledgement.
