Weak1::MD2::MD2 ( )

Definition at line 24 of file md2.cpp.

Here is the call graph for this function:

Member Function Documentation

unsigned int Weak1::MD2::BlockSize ( ) const

inlinevirtual

Provides the block size of the compression function.

Returns: the block size of the compression function, in bytes

BlockSize() will return 0 if the hash is not block based. For example, SHA3 is a recursive hash (not an iterative hash), and it does not have a block size.

Reimplemented from HashTransformation.

Definition at line 19 of file md2.h.

unsigned int Weak1::MD2::DigestSize ( ) const

inlinevirtual

Provides the digest size of the hash.

Returns: the digest size of the hash.

Implements HashTransformation.

void Weak1::MD2::Transform ( )

private

void Weak1::MD2::TruncatedFinal	(	byte *	digest,
		size_t	digestSize
	)

virtual

Computes the hash of the current message.

Parameters

digest	a pointer to the buffer to receive the hash
digestSize	the size of the truncated digest, in bytes

TruncatedFinal() call Final() and then copies digestSize bytes to digest. The hash is restarted the hash for the next message.

Implements HashTransformation.

Here is the call graph for this function:

void Weak1::MD2::Update	(	const byte *	input,
		size_t	length
	)

virtual

Updates a hash with additional input.

Parameters

input	the additional input as a buffer
length	the size of the buffer, in bytes

Implements HashTransformation.
