Constructor & Destructor Documentation

CDecPkcs12MacData()

CDecPkcs12MacData()[private]

Constructor.

CDecPkcs12MacData(const CDecPkcs12MacData &)

CDecPkcs12MacData(const CDecPkcs12MacData &aDecPkcs12MacData)[private]

Copy Constructor.

Parameters

const CDecPkcs12MacData & aDecPkcs12MacDataA CDecPkcs12MacData object.

~CDecPkcs12MacData()

~CDecPkcs12MacData()[virtual]

Destructor.

Member Functions Documentation

ConstructL(const TDesC8 &, const TDesC8 &)

voidConstructL(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 & aMacDatacontains a PKCS#12 MacData Structure.
const TDesC8 & aAuthSafeDatais 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 TIntIterationCount()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 & aMacDatacontains a PKCS#12 MacData Structure.
const TDesC8 & aAuthSafeDatais the ContentData present in the authSafe Sequence of PKCS#12 PFX Structure.

VerifyIntegrityL(const TDesC &)

IMPORT_C TBoolVerifyIntegrityL(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.
leave
KErrNotSupported if the Pkcs7 digest algorithm is otherthan MD2, MD5 and SHA-1
PKCS12KDF, CMessageDigest,

Parameters

const TDesC & aPasswordcontains the password to derive the key.

operator=(const CDecPkcs12MacData &)

CDecPkcs12MacData &operator=(const CDecPkcs12MacData &aDecPkcs12MacData)[private]

Assignment operator.

Parameters

const CDecPkcs12MacData & aDecPkcs12MacDataA CDecPkcs12MacData object.
