Detailed Description

A standard MD5 digest calculator.

A class to compute and check MD5 digests

Constructor & Destructor Documentation

MD5

(

)

Construct a fresh initialized instance

MD5

(

const MD5 &

original

)

Copy constructor

Parameters

original

MD5 instance to copy

MD5	(	const void *	buf,
		unsigned int	len
	)

Construct a digest from a buffer of data

Parameters

buf	Pointer to the data to be included in digest
len	Length of data in the buffer

MD5

(

const DataBlock &

data

)

Construct a digest from a binary DataBlock

Parameters

data	Binary data to be included in digest

MD5

(

const String &

str

)

Construct a digest from a String

Parameters

str	String to be included in digest

virtual ~MD5 ( )

virtual

Destroy the instance, free allocated memory

Member Function Documentation

virtual void clear ( )

virtual

Clear the digest and prepare for reuse

Implements Hasher.

virtual void finalize ( )

virtual

Finalize the digest computation, make result ready. Subsequent calls to update() will fail

Implements Hasher.

virtual unsigned int hashLength ( ) const

inlinevirtual

Return the length of the raw binary digest

Returns

Length of the digest in octets

Implements Hasher.

MD5& operator=

(

const MD5 &

original

)

Assignment operator.

virtual const unsigned char* rawDigest ( )

virtual

Returns a pointer to the raw 16-byte binary value of the message digest. The digest is finalized if if wasn't already

Returns

Pointer to the raw digest data or NULL if some error occured

Implements Hasher.

static unsigned int rawLength ( )

inlinestatic

Return the length of the raw binary digest

Returns

Constant value of 16

bool updateInternal ( const void *  buf, unsigned int  len  )

protectedvirtual

Update the digest from a buffer of data

Parameters

buf	Pointer to the data to be included in digest
len	Length of data in the buffer

Returns

True if success, false if finalize() was already called

Implements Hasher.
