Constructor & Destructor Documentation

fpoirotte\Cryptal\DefaultAlgorithms\Poly1305::__construct	(	MacEnum	$macAlgorithm,
		SubAlgorithmAbstractEnum	$innerAlgorithm,
			$key,
			$nonce = `''`
	)

Construct a new context to generate a Message Authentication Code.

Parameters

MacEnum	$macAlgorithm	Algorithm to use to produce the message authentication code.
SubAlgorithmAbstractEnum	$innerAlgorithm	Inner algorithm used during generation. This should be either an instance of CipherEnum or MacEnum, depending on the value for the $macAlgorithm parameter.

Warning: For MAC algorithms that use ciphers, the cipher must be configured to use the Electronic Codebook (ECB) mode. Other modes of operations will result in garbage output.

Parameters

string	$key	Secret key used to produce the Message Authentication Code.
string	$nonce	(optional) Nonce used to randomize the output.
