Constants

KEY_SIZE

KEY_SIZE

The internal secret key size measured in raw bytes length for the algorithm

Methods

getInstance()

getInstance() : static|null

Gives a unified access point for the current object instance.

Returns

static|null —

An instance.

__wakeup()

__wakeup()

Lock the reinitialization and unserialization abilities of the class.

__sleep()

__sleep()

Lock the serialization abilities of the class.

__toString()

__toString() : string

Return the name of the current defined class that extends the class.

Returns

string —

Name of the class.

encryptData()

encryptData(string  $secretKey, string  $plainData) : string

Encrypts the given plain data.

Parameters

string	$secretKey	The secret key.
string	$plainData	The plain data for encryption.

Throws

\Exception: Validation errors.

Returns

string —

The cipher/encrypted data.

decryptData()

decryptData(string  $secretKey, string  $cipherData) : string

Decrypts the given cipher data.

Parameters

string	$secretKey	The secret key.
string	$cipherData	The encrypted input string.

Throws

\Exception: Validation errors.

Returns

string —

The decrypted/plain data.

__construct()

__construct()

Locks the creation of new objects but allows static creation and extending.

keyScheduling()

keyScheduling(string  $key) : array

The key-scheduling algorithm for the initialize of the permutation array.

Parameters

string

$key

The secret key.

Returns

array —

The key stream permutation array.

transformData()

transformData(string  $key, string  $data) : string

The stream transformation operation realized via the internal pseudo-random generation algorithm.

Parameters

string	$key	The secret key.
string	$data	The data for transformation.

Throws

\Exception: Validation errors.

Returns

string —

The encrypted or decrypted data.

__clone()

__clone()

Lock the ability to clone properties and create a new dynamic instance of the class.
