Class CX509SubjectKeyIdExt

class CX509SubjectKeyIdExt : public CX509ExtensionBase;

Description

An X.509 certificate extension that provides a way of identifying certificates that contain a specific public key.

This is referred to as the subject key ID extension.

It consists of a key identifier value either derived from the public key or by some method of generating unique IDs.

Derivation

• CBase - Base class for all classes to be instantiated on the heap

• CX509ExtensionBase - A certificate extension base class

• CX509SubjectKeyIdExt - An X.509 certificate extension that provides a way of identifying certificates that contain a specific public key

static IMPORT_C CX509SubjectKeyIdExt *NewL(const TDesC8 &aBinaryData);

Description

Creates a new CX509SubjectKeyIdExt object from the specified buffer containing the binary coded representation.

Parameters

const TDesC8 &aBinaryData The encoded binary representation.

Return value

CX509SubjectKeyIdExt * The new CX509SubjectKeyIdExt object.

static IMPORT_C CX509SubjectKeyIdExt *NewLC(const TDesC8 &aBinaryData);

Description

Creates a new CX509SubjectKeyIdExt object from the specified buffer containing the binary coded representation, and puts a pointer to it onto the cleanup stack.

Parameters

const TDesC8 &aBinaryData The encoded binary representation.

Return value

CX509SubjectKeyIdExt * The new CX509SubjectKeyIdExt object.

static IMPORT_C CX509SubjectKeyIdExt *NewL(const TDesC8 &aBinaryData, TInt &aPos);

Description

Creates a new CX509SubjectKeyIdExt object from the specified buffer containing the binary coded representation, starting at the specified offset.

Parameters

const TDesC8 &aBinaryData The encoded binary representation. TInt &aPos The offset position from which to start decoding.

Return value

CX509SubjectKeyIdExt * The new CX509SubjectKeyIdExt object.

static IMPORT_C CX509SubjectKeyIdExt *NewLC(const TDesC8 &aBinaryData, TInt &aPos);

Description

Creates a new CX509SubjectKeyIdExt object from the specified buffer containing the binary coded representation, starting at the specified offset, and puts a pointer to it onto the cleanup stack.

Parameters

const TDesC8 &aBinaryData The encoded binary representation. TInt &aPos The offset position from which to start decoding.

Return value

CX509SubjectKeyIdExt * The new CX509SubjectKeyIdExt object.

IMPORT_C ~CX509SubjectKeyIdExt();

Description

Destructor.

Frees all resources owned by the object, prior to its destruction.

IMPORT_C TPtrC8 KeyId() const;

Description

Gets the key ID.

Return value

TPtrC8 A pointer descriptor representing the key ID.

private: virtual void DoConstructL(const TDesC8 &aBinaryData, TInt &aPos);

Description

Implementation for second-phase construction.

This is called by ConstructL().

Parameters

const TDesC8 &aBinaryData The encoded binary representation. This is the same as passed to ConstructL(). TInt &aPos The position from which to start decoding. Note that the value passed points, in effect, to the content, by passing the header data.
