Class CMessageDigestFactory

class CMessageDigestFactory : public CBase;

Description

Factory to create a CMessageDigest derived object according to the identity of the hash algorithm.

Derivation

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

• CMessageDigestFactory - Factory to create a CMessageDigest derived object according to the identity of the hash algorithm

Members

Defined in CMessageDigestFactory:
NewDigestL(), NewDigestLC(), NewHMACL(), NewHMACLC()

Inherited from CBase:
Delete(), Extension_(), operator new()

static IMPORT_C CMessageDigest *NewDigestL(CMessageDigest::THashId aHashId);

Description

Creates a CMessageDigest derived object according to the specified type of hash algorithm.

Parameters

CMessageDigest::THashId aHashId The identity of the hash algorithm

Return value

CMessageDigest * A pointer to a CMessageDigest object

static IMPORT_C CMessageDigest *NewDigestLC(CMessageDigest::THashId aHashId);

Description

Creates a CMessageDigest derived object according to the specified type of hash algorithm.

The returned pointer is put onto the cleanup stack.

Parameters

CMessageDigest::THashId aHashId The identity of the hash algorithm

Return value

CMessageDigest * A pointer to a CMessageDigest object

static IMPORT_C CMessageDigest *NewHMACL(CMessageDigest::THashId aHashId, const TDesC8 &aKey);

Description

Creates a CMessageDigest derived object according to the specified type of hash algorithm and authentication key.

Parameters

CMessageDigest::THashId aHashId The identity of the hash algorithm const TDesC8 &aKey The authentication key

Return value

CMessageDigest * A pointer to a CMessageDigest object

static IMPORT_C CMessageDigest *NewHMACLC(CMessageDigest::THashId aHashId, const TDesC8 &aKey);

Description

Creates a CMessageDigest derived object according to the specified type of hash algorithm and authentication key.

The returned pointer is put onto the cleanup stack.

Parameters

CMessageDigest::THashId aHashId The identity of the hash algorithm const TDesC8 &aKey The authentication key

Return value

CMessageDigest * A pointer to a CMessageDigest object
