CDecPkcs12MacData

(

const CDecPkcs12MacData &

aDecPkcs12MacData

)

[private]

Copy Constructor.

Member Functions Documentation

ConstructL(const TDesC8 &, const TDesC8 &)

void	ConstructL	(	const TDesC8 &	aMacData,
			const TDesC8 &	aAuthSafeData
		)	[private]

This decodes the entire MacData structure.

leave: KErrArgument if the data is not Pkcs12 macData structure.

CPKCS7DigestInfo

Parameters

const TDesC8 & aMacData	contains a PKCS#12 MacData Structure.
const TDesC8 & aAuthSafeData	is the ContentData present in the authSafe Sequence of PKCS#12 PFX Structure.

DigestInfo()

IMPORT_C const CPKCS7DigestInfo &

DigestInfo

(

)

const

The DigestInfo present in the MacData. It has the DigestAlgorithmIdentifier, and the Digest.

IterationCount()

IMPORT_C TInt

IterationCount

(

)

const

This method returns the Iteration Count. It is used in creating the key.

MacSalt()

IMPORT_C const TDesC8 &

MacSalt

(

)

const

This method returns the MacSalt. MacSalt is used as input to the key generation mechanism.

NewL(const TDesC8 &, const TDesC8 &)

IMPORT_C CDecPkcs12MacData *	NewL	(	const TDesC8 &	aMacData,
			const TDesC8 &	aAuthSafeData
		)	[static]

Creates a new PKCS#12MacData object.

leave: KErrArgument if the data is not Pkcs12 macData structure.

Parameters

const TDesC8 & aMacData	contains a PKCS#12 MacData Structure.
const TDesC8 & aAuthSafeData	is the ContentData present in the authSafe Sequence of PKCS#12 PFX Structure.

VerifyIntegrityL(const TDesC &)

IMPORT_C TBool

VerifyIntegrityL

(

const TDesC &

aPassword

)

const

This method does the Integrity Check for Password Integrity Mode by comparing the Digest present in the MacData of the PKCS#12 Structure with the hash generated from the content field of the authenticated Safe, password, the Iteration Count and the Salt present in the MacData.
