PKIHeader ::= SEQUENCE {
pvno INTEGER { cmp1999(1), cmp2000(2) },
sender GeneralName,
-- identifies the sender
recipient GeneralName,
-- identifies the intended recipient
messageTime [0] GeneralizedTime OPTIONAL,
-- time of production of this message (used when sender
-- believes that the transport will be "suitable"; i.e.,
-- that the time will still be meaningful upon receipt)
protectionAlg [1] AlgorithmIdentifier OPTIONAL,
-- algorithm used for calculation of protection bits
senderKID [2] KeyIdentifier OPTIONAL,
recipKID [3] KeyIdentifier OPTIONAL,
-- to identify specific keys used for protection
transactionID [4] OCTET STRING OPTIONAL,
-- identifies the transaction; i.e., this will be the same in
-- corresponding request, response, certConf, and PKIConf
-- messages
senderNonce [5] OCTET STRING OPTIONAL,
recipNonce [6] OCTET STRING OPTIONAL,
-- nonces used to provide replay protection, senderNonce
-- is inserted by the creator of this message; recipNonce
-- is a nonce previously inserted in a related message by

freeText [7] PKIFreeText OPTIONAL,
-- this may be used to indicate context-specific instructions
-- (this field is intended for human consumption)
generalInfo [8] SEQUENCE SIZE (1..MAX) OF
InfoTypeAndValue OPTIONAL
-- this may be used to convey context-specific information
-- (this field not primarily intended for human consumption)
