[Cmpforopenssl-devel] How to retrieve extra certificates from extraCerts on a client side?

[ABULIUS, M. (MUGUR) <mug...@al...>]

Hello,
This topic concerns the "extraCerts" field of the CMPv2 PKIMessage for the "Initialization Response".
The 3GPP "TS 33.310 V9.5.0 (2010-12)" specifies at §9.5.4.3:
"The extraCerts field of the PKIMessage carrying the initialization response shall contain the operator root certificate and  ..."
However I didn't see any way to retrieve the extraCerts certificates from the ip (init response) with the  "cmpforopenssl" tool. In my understanding (looking sources) the option "--extracert FILE" is an input option only. Also the option "--capubs DIRECTORY" is used only to retrieve caPubs certificates.
Do you intend to provide any option to retrieve extraCerts certificates from initial response?
Best Regards
