Class CX509BasicConstraintsExt

class CX509BasicConstraintsExt : public CX509ExtensionBase;

Description

An X.509 certificate extension that defines basic constraints.

It indicates whether the certificate belongs to a Certificate Authority or an end Entity.

Derivation

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

• CX509ExtensionBase - A certificate extension base class.

• CX509BasicConstraintsExt - An X.509 certificate extension that defines basic constraints.

IMPORT_C static CX509BasicConstraintsExt* NewL(const TDesC8 &aBinaryData);

Description

Creates a new CX509BasicConstraintsExt object from the specified buffer containing the binary coded representation.

Parameters

const TDesC8 &aBinaryData The encoded binary representation.

Return value

CX509BasicConstraintsExt * The new CX509BasicConstraintsExt object.

IMPORT_C static CX509BasicConstraintsExt* NewLC(const TDesC8 &aBinaryData);

Description

Creates a new CX509BasicConstraintsExt 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

CX509BasicConstraintsExt * The new CX509BasicConstraintsExt object.

IMPORT_C static CX509BasicConstraintsExt* NewL(const TDesC8 &aBinaryData, TInt &aPos);

Description

Creates a new CX509BasicConstraintsExt 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

CX509BasicConstraintsExt * The new CX509BasicConstraintsExt object.

IMPORT_C static CX509BasicConstraintsExt* NewLC(const TDesC8 &aBinaryData, TInt &aPos);

Description

Creates a new CX509BasicConstraintsExt 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

CX509BasicConstraintsExt * The new CX509BasicConstraintsExt object.

virtual ~CX509BasicConstraintsExt();

Description

Destructor.

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

IMPORT_C TBool IsCA() const;

Description

Tests whether the certificate belongs to a Certificate Authority.

Return value

TBool ETrue, if the certificate belongs to a Certificate Authority; EFalse, otherwise.

IMPORT_C TInt MaxChainLength() const;

Description

Gets the maximum number of certificates that can follow this one in the chain.

Return value

TInt The number of certificates.

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

Description

Implementation for second-phase construction.

This is called by CX509ExtensionBase::ConstructL(const TDesC8 &,TInt &).

Parameters

const TDesC8 &aBinaryData The encoded binary representation. This is the same as passed to CX509ExtensionBase::ConstructL(const TDesC8 &,TInt &). 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.
