__construct()

__construct	(		$key,
			$strength = 128,
			$mode = 'cbc',
		FOFUtilsPhpfunc	$phpfunc = null,
			$priority = 'openssl'
	)

Initialise the AES encryption object.

Note: If the key is not 16 bytes this class will do a stupid key expansion for legacy reasons (produce the SHA-256 of the key string and throw away half of it).

Paramètres

string	$key	The encryption key (password). It can be a raw key (16 bytes) or a passphrase.
int	$strength	Bit strength (128, 192 or 256) – ALWAYS USE 128 BITS. THIS PARAMETER IS DEPRECATED.
string	$mode	Encryption mode. Can be ebc or cbc. We recommend using cbc.
FOFUtilsPhpfunc	$phpfunc	For testing
string	$priority	Priority which adapter we should try first

decryptString()

decryptString	(		$stringToDecrypt,
			$base64encoded = true
	)

Decrypts a ciphertext into a plaintext string using AES

Paramètres

string	$stringToDecrypt	The ciphertext to decrypt. The first 16 bytes of the raw string must contain the IV (initialisation vector).
bool	$base64encoded	Should I Base64-decode the data before decryption?

Renvoie

string The plain text string

encryptString()

encryptString	(		$stringToEncrypt,
			$base64encoded = true
	)

Encrypts a string using AES

Paramètres

string	$stringToEncrypt	The plaintext to encrypt
bool	$base64encoded	Should I Base64-encode the result?

Renvoie

string The cryptotext. Please note that the first 16 bytes of the raw string is the IV (initialisation vector) which is necessary for decoding the string.

boolean

setPassword()

setPassword	(		$password,
			$legacyMode = false
	)

Sets the password for this instance.

WARNING: Do not use the legacy mode, it's insecure

Paramètres

string	$password	The password (either user-provided password or binary encryption key) to use
bool	$legacyMode	True to use the legacy key expansion. We recommend against using it.
