[Sorry for the prior empty mails I am experiencing some problems with mail]
Hello,
Im implementing some X509 attributes for a Openssl based X509 attribute
certificates API (will be available when finished). I have some problems
with one attribute, I don't know if I am implementing it correctly or not so
I need help. Let me present the problem: fist the definition (by the IETF)
of the attribute, then the implementation details (declaration and
implementation) and the piece of code that does not work. Any help would be
indeed very much grateful.
-Definition (IETF)
IetfAttrSyntax ::= SEQUENCE {
policyAuthority [0] GeneralNames OPTIONAL,
values SEQUENCE OF CHOICE {
octets OCTET STRING,
oid OBJECT IDENTIFIER,
string UTF8String
}
}
-Declaration (.h)
typedef struct IetfAttrSyntax_st {
GENERAL_NAMES *policyAuthority;
int type;
union{
ASN1_OCTET_STRING *octets;
ASN1_OBJECT *oid;
ASN1_UTF8STRING *string;
}values;
} IetfAttrSyntax;
DECLARE_ASN1_ITEM(IetfAttrSyntax)
DECLARE_ASN1_FUNCTIONS(IetfAttrSyntax)
-Implementation (.c)
ASN1_CHOICE(IetfAttrValues)= {
ASN1_SIMPLE(IetfAttrSyntax ,values.octets , ASN1_OCTET_STRING ),
ASN1_SIMPLE(IetfAttrSyntax ,values.oid , ASN1_OBJECT ),
ASN1_SIMPLE(IetfAttrSyntax ,values.string , ASN1_UTF8STRING )
}ASN1_CHOICE_END_selector(IetfAttrSyntax, IetfAttrValues, type);
ASN1_SEQUENCE(IetfAttrSyntax) = {
ASN1_OPT(IetfAttrSyntax, policyAuthority, GENERAL_NAMES, 0),
ASN1_EX_COMBINE(0, 0, IetfAttrValues)
}ASN1_SEQUENCE_END(IetfAttrSyntax);
IMPLEMENT_ASN1_FUNCTIONS(IetfAttrSyntax)
IMPLEMENT_ASN1_DUP_FUNCTION(IetfAttrSyntax)
-Test code
/* creating a IetfAttrSyntax */
attr_val2 = IetfAttrSyntax_new();
attr_val2->policyAuthority = GENERAL_NAMES_new();
gen = GENERAL_NAME_new();
gen->type = GEN_DIRNAME;
gen->d.directoryName = X509_NAME_dup(ident_name);
sk_GENERAL_NAME_push(attr_val2->policyAuthority,gen);
attr_val2->type = 0;//V_ASN1_OCTET_STRING;
if( attr_val2->values.octets == NULL )
attr_val2->values.octets = ASN1_OCTET_STRING_new();
ASN1_OCTET_STRING_set(attr_val2->values.octets,data_,24);
attr_val2 = IetfAttrSyntax_dup(attr_val2); <--- [doesn't work]
i2d and d2i also doesn't work (dup depends on them so is logical)
Any help would be indeed very much grateful.
Thank you very much!
Dani
