Hello Sukalp,
I have tried to use the code snippet provided by use . I am able to create
the ASN_object and get the data also.but the data is not in readable form.
I use X509 instead of X509V3.
Here is the code that i have used :
*Ret = X509_get_ext_by_NID(cert, field_NID, 0);
if ((Ret > 0) && (ext = X509_get_ext(cert, Ret)))
{
ASN1_OBJECT *obj;
obj=OBJ_nid2obj(field_NID);
if (obj == NULL) return(-2);
return(X509_get_ext_by_OBJ(cert,obj,0));
}*
The object snippet that i have found is
Please help me to get the data in readable format.
Regards.
Puneet
