Detailed Description

A structure for high-performance hashing.

Member Function Documentation

hashFinish()

void Superpowered::hasher::hashFinish

(

unsigned char *

output

)

Finish hashing and return with the hash.

Parameters

output

The output. Must be big enough to store the result (SHA512 has the maximum with 64 bytes).

hashProcess()

void Superpowered::hasher::hashProcess

(

const unsigned char *

input

)

Perform hashing on the input data with the exact same input length of the hasher algorithm.

Can be called multiple times.

Parameters

input

Pointer to the input data.

hashStart()

void Superpowered::hasher::hashStart

(

hashType

type

)

Initialize the structure for hashing.

The structure will be as good as new after this.

Parameters

type	The hash type.

hashUpdate()

void Superpowered::hasher::hashUpdate	(	const unsigned char *	input,
		int	inputLengthBytes
	)

Perform hashing on the input data with any kind of input length.

Can be called multiple times.

Parameters

input	Pointer to the input data.
inputLengthBytes	Size of the input data in bytes.

hmacFinish()

void Superpowered::hasher::hmacFinish

(

unsigned char *

output

)

Finish hmac and return with the hash.

Parameters

output

The output. Must be big enough to store the result (SHA512 has the maximum with 64 bytes).

hmacReset()

void Superpowered::hasher::hmacReset

(

)

Re-initialize the structure for hmac.

hmacStart()

void Superpowered::hasher::hmacStart	(	hashType	type,
		const unsigned char *	key,
		int	keyLengthBytes
	)

Initialize the structure for hash-based message authentication code hashing.

The structure will be as good as new after this.

Parameters

type	The hash type.
key	The key.
keyLengthBytes	The size of the key in bytes.

hmacUpdate()

void Superpowered::hasher::hmacUpdate	(	const unsigned char *	input,
		int	inputLengthBytes
	)

Perform hmac on the input data with any kind of input length.

Can be called multiple times.

Parameters

input	Pointer to the input data.
inputLengthBytes	Size of the input data in bytes.
