Methods

__construct()

__construct(string  $data = null,  $length = null)

Constructor

Parameters

string	$data	The data to process
	$length

process()

process(string  $chunk)

Computes the hash of all of the trigrams in the chunk using a window of length 5

Parameters

string

$chunk

The chunk to process

tranHash()

tranHash(integer  $a,integer  $b,integer  $c,integer  $n): integer

Implementation of the Tran53 hash algorithm

Parameters

integer	$a	Input A
integer	$b	Input B
integer	$c	Input C
integer	$n	Input N

Returns

integer

hexDigest()

hexDigest(): string

Returns the digest as a hex string. Computes it if it isn't computed already.

Returns

string —

The digest

digest()

digest(): array

Returns the digest as an array. Computes it if it isn't computed already.

Returns

array —

The digest

computeDigest()

computeDigest()

Using a threshold (mean of the accumulator), computes the nilsimsa digest after completion. Sets complete flag to true and stores result in $this->digest

hash()

hash(  $data,  $length = 256)

Parameters

	$data
	$length
