◆ __construct()

__construct ( $mode )

Default Constructor.

Paramètres

string $mode public

Exceptions

BadModeException if an invalid / unsupported mode is provided

Références SymmetricKey\$mode, et Symfony\Contracts\Service\__construct().

Documentation des fonctions membres

◆ decryptBlock()

decryptBlock ( $in )

protected

Decrypts a block

Voir également: ::decryptBlock(); ::decrypt(); self::decrypt() private

Paramètres

string $in

Renvoie: string

Références DES\processBlock().

◆ encryptBlock()

encryptBlock ( $in )

protected

Encrypts a block

Voir également: ::encryptBlock(); ::encrypt(); self::encrypt() private

Paramètres

string $in

Renvoie: string

Références DES\processBlock().

◆ isValidEngineHelper()

isValidEngineHelper ( $engine )

protected

Test for engine validity

This is mainly just a wrapper to set things up for ::isValidEngine()

Voir également: ::isValidEngine()

Paramètres

int $engine protected

Renvoie: bool

Références SymmetricKey\$engine, et SymmetricKey\openssl_translate_mode().

◆ processBlock()

processBlock	(	$block,
		$mode
	)

private

Encrypts or decrypts a 64-bit block

$mode should be either self::ENCRYPT or self::DECRYPT. See Feistel.png to get a general idea of what this function does.

Référencé par DES\decryptBlock(), et DES\encryptBlock().

◆ setKey()

setKey ( $key )

Sets the key.

Keys must be 64-bits long or 8 bytes long.

DES also requires that every eighth bit be a parity bit, however, we'll ignore that.

◆ setupInlineCrypt()

setupInlineCrypt ( )

protected

Setup the performance-optimized function for de/encrypt()

Voir également: ::setupInlineCrypt() private

Références $c, DES\$des_rounds, $i, $r, et SymmetricKey\createInlineCryptFunction().

◆ setupKey()

setupKey ( )

protected
