Hi Steve,
First thanks for the quick response.
Well, this function is mine, it's not the problem. you can see the function
below :
int POLICY_add_attrib(PKCS7_SIGNER_INFO *si, POLICYINFO *pInfo) {
ASN1_STRING *seq;
unsigned char *p, *pp ;
int len;
len = i2d_POLICYINFO(pInfo, NULL);
pp = (unsigned char *) OPENSSL_malloc(len);
p = pp;
i2d_POLICYINFO(pInfo, &p);
seq = ASN1_STRING_new();
ASN1_STRING_set (seq, pp, len);
OPENSSL_free(pp);
int nidPolicy = OBJ_create("1.2.840.113549.1.9.16.2.15",
"id_aa_ets_sigPolicyId", "id_aa_ets_sigPolicyId");
return PKCS7_add_signed_attribute(si, nidPolicy, V_ASN1_SEQUENCE, seq);
}
The problem is when I pass to this function an POLICYINFO object with an
POLICYQUALINFO that has an pqualid value other than "NID_id_qt_cps".
If I don't use :
pQInfo->pqualid = OBJ_nid2obj(NID_id_qt_cps);
And use :
int NID_id_spq_ets_uri = OBJ_create("1.2.840.113549.1.9.16.5.1",
"id_spq_ets_uri", "id_spq_ets_uri");
pQInfo->pqualid = OBJ_nid2obj(NID_id_spq_ets_uri);
For example, or wherever other NID or created NID the code crashs on :
len = i2d_POLICYINFO(pInfo, NULL);
Understand?
Thanks in advance.
