Hi Massimiliano,
I don't know if that's the best solution, but it worked for me that way:
in crmf.h:
typedef struct crmf_certreqmsg_st
{
»·······CRMF_CERTREQUEST *certReq;
»·······CRMF_PROOFOFPOSSESION *popo; /* 0 */
»·······CRMF_ATTRIBUTETYPEANDVALUE *regInfo; /* 1 */
} CRMF_CERTREQMSG;
DECLARE_ASN1_FUNCTIONS(CRMF_CERTREQMSG)
DECLARE_STACK_OF(CRMF_CERTREQMSG) /* CertReqMessages */
DECLARE_ASN1_SET_OF(CRMF_CERTREQMSG) /* CertReqMessages */
in crmf_asn.c:
ASN1_SEQUENCE(CRMF_CERTREQMSG) = {
»·······ASN1_SIMPLE(CRMF_CERTREQMSG, certReq, CRMF_CERTREQUEST),
»·······ASN1_IMP_OPT(CRMF_CERTREQMSG, popo, CRMF_PROOFOFPOSSESION, 0),
»·······ASN1_IMP_SEQUENCE_OF_OPT(CRMF_CERTREQMSG, regInfo,
CRMF_ATTRIBUTETYPEANDVALUE, 1)
} ASN1_SEQUENCE_END(CRMF_CERTREQMSG)
IMPLEMENT_ASN1_FUNCTIONS(CRMF_CERTREQMSG)
I needed it for CMP. In order to use the "CertReqMessages", I am doing:
In cmp.h:
typedef struct cmp_pkibody_st
{
»·······int type;
»·······union{
»·······»·······STACK_OF(CRMF_CERTREQMSG) *ir; /* 0 */
...
In cmp_asn.c:
ASN1_CHOICE(CMP_PKIBODY) = {
»·······ASN1_EXP_SEQUENCE_OF(CMP_PKIBODY, value.ir, CRMF_CERTREQMSG, 0),
...
There might be other ways to do it - the OpenSSL ASN.1 documentation
seems to be not complete - but it works fine that way.
As there are not many things to use CRMF for: what are you
implementing? Do you know my code to use CMP with OpenSSL? You can
obtain the full code including the snippets I pasted above from
<http://www.izac.de/cmp>.
Best regards,
Martin
