| ASN.1 structure DER En/DeCoder.
PKIHeader ::= SEQUENCE {
pvno INTEGER { ietf-version2 (1) },
sender GeneralName, -- identifies the sender
recipient GeneralName, -- identifies the intended recipient
messageTime [0] GeneralizedTime OPTIONAL, -- time of production of this message
protectionAlg [1] AlgorithmIdentifier OPTIONAL, -- algorithm used for calculation of protection bits
senderKID [2] KeyIdentifier OPTIONAL, -- (OCTET STRING)
recipKID [3] KeyIdentifier OPTIONAL, -- (OCTET STRING) 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 and confirmation 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 the intended recipient of this message
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)
