Свойство	Type	Description
$algorithm	string	Hash algorithm to use, see hash_algos()
$derivedKeyLength	integer	Derived key length
$dynamicSaltLength	integer	Length of the dynamic random salt to generate in bytes
$iterationCount	integer	Hash iteration count, high counts (>10.000) make brute-force attacks unfeasible

Méthode	Description
__construct ( integer $dynamicSaltLength, integer $iterationCount, integer $derivedKeyLength, string $algorithm )	Construct a PBKDF2 hashing strategy with the given parameters
hashPassword ( string $password, string $staticSalt = null ) : string	Hash a password for storage using PBKDF2 and the configured parameters.
validatePassword ( string $password, string $hashedPasswordAndSalt, string $staticSalt = null ) : boolean	Validate a password against a derived key (hashed password) and salt using PBKDF2.

Construct a PBKDF2 hashing strategy with the given parameters

public __construct ( integer $dynamicSaltLength, integer $iterationCount, integer $derivedKeyLength, string $algorithm )
$dynamicSaltLength	integer	Length of the dynamic random salt to generate in bytes
$iterationCount	integer	Hash iteration count, high counts (>10.000) make brute-force attacks unfeasible
$derivedKeyLength	integer	Derived key length
$algorithm	string	Hash algorithm to use, see hash_algos()

Will use a combination of a random dynamic salt and the given static salt.

public hashPassword ( string $password, string $staticSalt = null ) : string
$password	string	Cleartext password that should be hashed
$staticSalt	string	Static salt that will be appended to the random dynamic salt
Résultat	string	A Base64 encoded string with the derived key (hashed password) and dynamic salt

Iteration count and algorithm have to match the parameters when generating the derived key.

public validatePassword ( string $password, string $hashedPasswordAndSalt, string $staticSalt = null ) : boolean
$password	string	The cleartext password
$hashedPasswordAndSalt	string	The derived key and salt in Base64 encoding as returned by hashPassword for verification
$staticSalt	string	Static salt that will be appended to the dynamic salt
Résultat	boolean	TRUE if the given password matches the hashed password

Hash algorithm to use, see hash_algos()
