CMD5 Class Reference

class CMD5 : public CMessageDigest

An MD5 message digest

Takes a message of arbitrary length as input and produces a 128-bit message digest.

The length of input data should not be longer than 2^32 in bits(2^31 in bytes) which is roughly half a gig.

Member Functions Documentation

Block()

voidBlock()[private]

BlockSize(void)

IMPORT_C TIntBlockSize(void)[virtual]

Gets the internal block size of the message digest.

Parameters

void

CopyL(void)

IMPORT_C CMessageDigest *CopyL(void)[virtual]

Creates a new CMessageDigest object with the exact same state as the current object.

This function copies all internal state of the message digest. To create a new CMessageDigest object without the state of the current object, see ReplicateL().

Parameters

void

DoFinal(void)

voidDoFinal(void)[private]

Parameters

void

DoUpdate(const TUint8 *, TUint)

voidDoUpdate(const TUint8 *aData,
TUintaLength
)[private]

Parameters

const TUint8 * aData
TUint aLength

Final(const TDesC8 &)

IMPORT_C TPtrC8Final(const TDesC8 &aMessage)[virtual]

Adds aMessage to the internal representation of data to be hashed, returns a TPtrC8 of the finalised hash of all the previously appended messages, and calls Reset().

Since
v8.0

Parameters

const TDesC8 & aMessageData to be included in the hash

Final()

IMPORT_C TPtrC8Final()[virtual]

Gets a TPtrC8 of the finalised hash of all the previously appended messages and then calls Reset().

Since
v8.0

Hash(const TDesC8 &)

IMPORT_C TPtrC8Hash(const TDesC8 &aMessage)[virtual]

Adds aMessage to the internal representation of data to be hashed, then returns a TPtrC8 of the finalised hash of all the previously appended messages.

Parameters

const TDesC8 & aMessageData to be included in the hash.

HashSize(void)

IMPORT_C TIntHashSize(void)[virtual]

Gets the size of the message digest output.

Parameters

void

NewL(void)

IMPORT_C CMD5 *NewL(void)[static]

Creates a new MD5 object.

Parameters

void

ReplicateL(void)

IMPORT_C CMessageDigest *ReplicateL(void)[virtual]

Creates a brand new reset CMessageDigest object containing no state information from the current object.

To make a copy of a message digest with its internal state intact, see CopyL().

Parameters

void

Reset(void)

IMPORT_C voidReset(void)[virtual]

Resets the internal state of the message digest.

A reset hash object loses all internal state representing the hashed data. A reset message digest is suitable to begin a new, distinct hash of different data. Any previously returned TPtrC8 from a call to Final() remains valid until any subsequent call to Update() or Final().

Parameters

void

RestoreState()

voidRestoreState()[virtual]

Restores the internal state of the message digest to a previously stored state.

StoreState()

StoreState()

voidStoreState()[virtual]

Stores the internal state of the message digest.

Update(const TDesC8 &)

IMPORT_C voidUpdate(const TDesC8 &aMessage)[virtual]

Adds data to the internal representation of messages to be hashed.

Since
v8.0

Parameters

const TDesC8 & aMessageData to be included in the hash.
