Detailed Description

Whirlpool hash class.

The Whirlpool algorithm was developed by Paulo S. L. M. Barreto and Vincent Rijmen.

See P.S.L.M. Barreto, V. Rijmen, "The Whirlpool hashing function" NESSIE submission, 2000 (tweaked version, 2001), https://www.cosic.esat.kuleuven.ac.be/nessie/workshop/submissions/whirlpool.zip

Constructor & Destructor Documentation

Whirlpool() [1/7]

juce::Whirlpool::Whirlpool ( )

noexcept

Creates an empty Whirlpool object.

The default constructor just creates a hash filled with zeros. (This is not equal to the hash of an empty block of data).

~Whirlpool()

juce::Whirlpool::~Whirlpool ( )

noexcept

Destructor.

Whirlpool() [2/7]

juce::Whirlpool::Whirlpool ( const Whirlpool &  other )

noexcept

Creates a copy of another Whirlpool.

Whirlpool() [3/7]

juce::Whirlpool::Whirlpool ( const MemoryBlock &  )

explicit

Creates a hash from a block of raw data.

Whirlpool() [4/7]

juce::Whirlpool::Whirlpool	(	const void *	data,
		size_t	numBytes
	)

Creates a hash from a block of raw data.

Whirlpool() [5/7]

juce::Whirlpool::Whirlpool	(	InputStream &	input,
		int64	maxBytesToRead = -1
	)

Creates a hash from the contents of a stream.

This will read from the stream until the stream is exhausted, or until maxBytesToRead bytes have been read. If maxBytesToRead is negative, the entire stream will be read.

Whirlpool() [6/7]

juce::Whirlpool::Whirlpool ( const File &  file )

explicit

Reads a file and generates the hash of its contents.

If the file can't be opened, the hash will be left uninitialised (i.e. full of zeros).

Whirlpool() [7/7]

juce::Whirlpool::Whirlpool ( CharPointer_UTF8  utf8Text )

explicitnoexcept

Creates a checksum from a UTF-8 buffer.

E.g.

Whirlpool checksum (myString.toUTF8());

Member Function Documentation

getRawData()

MemoryBlock juce::Whirlpool::getRawData

(

)

const

Returns the hash as a 64-byte block of data.

operator!=()

bool juce::Whirlpool::operator!= ( const Whirlpool &  ) const

noexcept

operator=()

Whirlpool& juce::Whirlpool::operator= ( const Whirlpool &  other )

noexcept

Copies another Whirlpool.

operator==()

bool juce::Whirlpool::operator== ( const Whirlpool &  ) const

noexcept

process()

void juce::Whirlpool::process ( const void *  , size_t    )

private

toHexString()

String juce::Whirlpool::toHexString

(

)

const

Returns the checksum as a 128-digit hex string.
