MAX_PASSWORD_LENGTH

Methods

__construct(int $cost)
string encodePassword(string $raw, string $salt)

Encodes the raw password.
bool isPasswordValid(string $encoded, string $raw, string $salt)

Checks a raw password against an encoded password.

Details

__construct(int $cost)

Parameters

int $cost The algorithmic cost that should be used

Exceptions

RuntimeException When no BCrypt encoder is available
InvalidArgumentException if cost is out of range

string encodePassword(string $raw, string $salt)

Encodes the raw password.

It doesn't work with PHP versions lower than 5.3.7, since the password compat library uses CRYPT_BLOWFISH hash type with the "$2y$" salt prefix (which is not available in the early PHP versions).

Parameters

string $raw The password to encode
string $salt The salt

Return Value

string The encoded password

Exceptions

BadCredentialsException when the given password is too long
