Detailed Description

Hashing algorithm, based on keccak. Trits are absorbed by the sponge function and later squeezed to provide message digest, derive keys etc.

Member Function Documentation

absorb()

void IOTA::Crypto::Kerl::absorb	(	const std::vector< uint8_t > &	bytes,
		std::size_t	offset = 0,
		std::size_t	length = 0
	)

Absorb the input bytes into the current state of the sponge.

Parameters

bytes	Input bytes to be absorbed on current state of the sponge.
offset	Offset at which the current state of the sponge should be modified.
length	Length of the given input that should be used for absorption.

finalSqueeze()

void IOTA::Crypto::Kerl::finalSqueeze	(	std::vector< uint8_t > &	bytes,
		std::size_t	offset = 0
	)

Squeeze the final current state of the sponge to the given trits. Kerl should not be used after this function is called, unless it is reset.

Parameters

bytes	Bytes to be squeezed based on current state of the sponge.
offset	Offset at which the bytes should be modified.

reset()

void IOTA::Crypto::Kerl::reset

(

)

Reset current state of the sponge.

squeeze()

void IOTA::Crypto::Kerl::squeeze	(	std::vector< uint8_t > &	bytes,
		std::size_t	offset = 0
	)

Squeeze the current state of the sponge to the given trits.

Parameters

bytes	Bytes to be squeezed based on current state of the sponge.
offset	Offset at which the bytes should be modified.
