OIDs for X.509 Certificate Library Modules

Overview

This chapter specifies object identifiers and corresponding data structures for fields of X.509 Certificates and Certificate Revocation Lists (CRLs). An OID can specify one field or multiple fields contained in a certificate or CRL. The OID also indicates the data representation of the field values. One to three distinct representations are defined for each meaningful aggregation of certificate field values:

Some certificate fields can be returned to an application in any of the three formats. Applications specify the desired format by using distinct OID names. The OID names for a single field in different representations share a common prefix. The selected representation is identified by a unique OID suffix. This allows applications to store tables of the common base and to select the desired representation at runtime by appending the suffix corresponding to the desired representation.

Interoperable Format Specifications for X.509

Certificate Library Service Provider X.509 Field OIDs

This section defines the OID names to be used to access fields in X.509 certificates and CRLs. The format of the data accessed with each OID is described.

Following sections then describe the OIDs upon which Certificate and CRL OIDs are based:

Base of the Object Identifier Name Space

This specification defines five object identifiers, which form the base arcs for Intel Corporation's CDSA name space.

INTEL OBJECT IDENTIFIER ::=
{ joint-ise-ccitt (2) country (16) usa (840) org (1) intel (113741) }

The object identifier INTEL identifies the base arc of the Intel Corporation name space under the registration authority of the joint ISO and the International Telegraph and Telephone Consultative Committee.

INTEL_CDSASECURITY OBJECT IDENTIFIER ::=

The object identifier INTEL_CDSASECURITY identifies the base arc for CDSA object identifiers with the Intel Corporation name space. The CDSA name space is subdivided into two subarcs:

INTEL_SEC_FORMATS OBJECT IDENTIFIER ::=
{ joint-ise-ccitt (2) country (16) usa (840) org (1) intel (113741) CDSA-security (2) formats (1) }

The object identifier INTEL_SEC_FORMATS identifies the base arc of object identifiers representing the format or representation of a CDSA security object within the Intel Corporation CDSA name space.

INTEL_SEC_ALGS OBJECT IDENTIFIER ::=

The object identifier INTEL_SEC_ALGS identifies the base arc of object identifiers representing the format or representation of CDSA security algorithms within the Intel Corporation CDSA name space.

The object identifier INTEL_SEC_FORMATS identifies the base arc of object identifiers representing the format or representation of a CDSA security object within the Intel Corporation CDSA name space. A subarc for security object bundles is defined within the CDSA formats object identifier name space.

Object Identifiers for X.509 V3 Certificates

Base Object Identifiers

This specification defines object identifiers to name fields and sets of fields within an X.509 certificate. Each object identifier also indicates the representation for the selected field or fields. Possible representations include:

Object identifiers are defined corresponding to the certificate fields defined by the X.509 V1 standard and the X.509 V3 standard. Two primary subarcs are defined for this purpose:

The object identifier INTEL_X509V3_SIGN_R08 identifies the base arc for object identifiers representing the format and name of the subfields of a digital signature contained in an X.509 version 3 certificate

A subarc for X.509 version certificate extensions is defined under INTEL_X509V3_CERT_R08 as follows:

    CSSM_X509EXT_POLICYQUALIFIERINFO *policyQualifier;
} CSSM_X509EXT_POLICYQUALIFIERS, *CSSM_X509EXT_POLICYQUALIFIERS_PTR;


DESCRIPTION

numberOfPolicyQualifiers

The number of policy qualifiers.

policyQualifier

A pointer to an array of policy qualifier structures

CSSM_X509EXT_POLICYINFO


typedef struct cssm_x509ext_policyInfo {
    CSSM_OID policyIdentifier;
    CSSM_X509EXT_POLICYQUALIFIERS policyQualifiers;
} CSSM_X509EXT_POLICYINFO, *CSSM_X509EXT_POLICYINFO_PTR;


DESCRIPTION

policyIdentifier

An OID that uniquely identifies a policy.

policyQualifiers

A pointer to a structure that that indicates the policy qualifiers associated with the policy identifier.

Certificate OIDs and Certificate Data Structures

This section addresses the association between certificate OIDs and certificate data structures.

The certificate object identifiers indicate selected fields from an X.509 certificate. The object identifier is a required input parameter to "create" certificates, "get" certificate values out of the certificate, or "set" values for a certificate template (in anticipation of creating a certificate). Certificate creation functions accept input values as CSSM_FIELD structures. Each CSSM_FIELD structure contains an OID and a value. The value is contained in a CSSM_DATA structure. A CSSM_DATA structure contains a length and a pointer to the actual data value. The length indicates the number of bytes in the data value. The length is represented as a platform-dependent 32-bit unsigned integer. The data value referenced by the pointer is in one of three encoding: BER/DER, LDAP string or native, bushy C language structure.

The CSSM "get" functions accept an OID as input and return a single CSSM_DATA structure. The same use model is applied in this case.

The following table maps the object identifier for a selected set of certificate fields to the structure and format accepted as input by the "create" and "set" operations, and returned as output by the "get" operation.
