An OpenSSL-based implementation of the Certificate Management Protocol (CMP), defined in IETF RFCs 4210, 4211, and 6712. It is being extended according to the emerging RFCs 'CMP Updates' (CMPv3), 'CMP Algorithms', and 'Lightweight CMP Profile'.
When using HTTP(S) as message transfer mechanism,
currently the TCP connection is closed after each request-response round-trip.
It would be more efficient to keep it open for all parts of the same transaction.
At HTTP level this is known as persistent connections: https://tools.ietf.org/html/rfc7230#section-6.3 .
This is relevant only for more complex transaction that use confirmation or polling.
