CX509CertExtension Class Reference

class CX509CertExtension : public CBase

A generic X.509 certificate extension.

The creation of a generic extension is the first step in the creation of a specific extension. Client code gets the decoded Object Identifier (OID) encapsulated by an instance of this class and uses it to create the specific extension.

Consists of an any-defined-by structure along with a boolean flag saying whether the extension is critical or not.

Critical()

IMPORT_C TBoolCritical()const

Tests whether certificate processing code must process this extension for certificate validation to succeed.

ETrue, if this extension must be processed for validation to succeed; EFalse, otherwise.

Data()

IMPORT_C TPtrC8Data()const

Gets the encoded binary representation of the specific extension.

A pointer descriptor representing the specific extension.

EncodeASN1DERLC()

IMPORT_C CASN1EncSequence *EncodeASN1DERLC()const

Creates and returns a DER encoded X.509 certificate extension object in the form of a ASN.1 Sequence and puts it onto the cleanup stack. This method can be called repeatedly to get copies of the sequence.

A pointer to a DER encoded ASN.1 sequence

Id()

IMPORT_C TPtrCId()const

Gets the Object Identifier (OID) of the certficate extension.

The OID of the certficate extension.

NewL(const CX509CertExtension &)

IMPORT_C CX509CertExtension *NewL(const CX509CertExtension &aExtension)[static]

Creates a new generic X.509 certificate extension object from an existing object.

This is equivalent to a copy constructor.

The new generic certificate extension object.

Parameters

const CX509CertExtension & aExtensionThe generic certificate extension to be copied.

NewL(const TDesC8 &)

IMPORT_C CX509CertExtension *NewL(const TDesC8 &aBinaryData)[static]

Creates a new generic X.509 certificate extension object from the specified buffer containing the binary coded representation.

The new generic X.509 certificate extension object.

Parameters

const TDesC8 & aBinaryDataThe encoded binary representation.

NewL(const TDesC8 &, TInt &)

IMPORT_C CX509CertExtension *NewL(const TDesC8 &aBinaryData,
TInt &aPos
)[static]

Creates a new generic X.509 certificate extension object from the specified buffer containing the binary coded representation, starting at the specified offset.

The new generic X.509 certificate extension object.

Parameters

const TDesC8 & aBinaryDataThe encoded binary representation.
TInt & aPosThe offset position from which to start decoding.

NewL(const TDesC &, const TBool, const TDesC8 &)

IMPORT_C CX509CertExtension *NewL(const TDesC &aCertExtOID,
const TBoolaCritical,
const TDesC8 &aCertExtValue
)[static]

Creates a new generic X.509 certificate extension object from the specified extension object id, the critcal flag and the extension data.

The new generic X.509 certificate extension object.

Parameters

const TDesC & aCertExtOIDThe OID of the certficate extension.
const TBool aCriticalFlag to convey criticality of the extension.
const TDesC8 & aCertExtValueThe data of the specific extension.

NewLC(const CX509CertExtension &)

IMPORT_C CX509CertExtension *NewLC(const CX509CertExtension &aExtension)[static]
