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.

Since: v6.0

(

)

const

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

Data()

IMPORT_C TPtrC8

Data

(

)

const

Gets the encoded binary representation of 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.

Id()

IMPORT_C TPtrC

(

)

const

Gets the Object Identifier (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.

Parameters

const CX509CertExtension & aExtension

The 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.

Parameters

const TDesC8 & aBinaryData

The 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.

Parameters

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

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

IMPORT_C CX509CertExtension *	NewL	(	const TDesC &	aCertExtOID,
			const TBool	aCritical,
			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.

Parameters

const TDesC & aCertExtOID	The OID of the certficate extension.
const TBool aCritical	Flag to convey criticality of the extension.
const TDesC8 & aCertExtValue	The data of the specific extension.

NewLC(const CX509CertExtension &)

IMPORT_C CX509CertExtension *

NewLC

(

const CX509CertExtension &

aExtension

)

[static]

Creates a new generic X.509 certificate extension object from an existing object, and puts a pointer to it onto the cleanup stack.

This is equivalent to a copy constructor.

Parameters

const CX509CertExtension & aExtension

The generic certificate extension to be copied.

NewLC(const TDesC8 &)

IMPORT_C CX509CertExtension *

NewLC

(

const TDesC8 &
