Subject: Simfony2 hashes
Hi all!
Does anybody already cracked this by JTR?
https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Security/Core/Encoder/MessageDigestPasswordEncoder.php:
public function __construct($algorithm = 'sha512',
$encodeHashAsBase64 = true, $iterations = 5000)
...
public function encodePassword($raw, $salt)
{
if ($this->isPasswordTooLong($raw)) {
throw new BadCredentialsException('Invalid password.');
}
if (!in_array($this->algorithm, hash_algos(), true)) {
throw new \LogicException(sprintf('The algorithm "%s" is not
supported.', $this->algorithm));
}
$salted = $this->mergePasswordAndSalt($raw, $salt);
$digest = hash($this->algorithm, $salted, true);
// "stretch" hash
for ($i = 1; $i < $this->iterations; $i++) {
$digest = hash($this->algorithm, $digest.$salted, true);
}
return $this->encodeHashAsBase64 ? base64_encode($digest) :
bin2hex($digest);
...
protected function demergePasswordAndSalt($mergedPasswordSalt)
{
if (empty($mergedPasswordSalt)) {
return array('', '');
}
$password = $mergedPasswordSalt;
$salt = '';
$saltBegins = strrpos($mergedPasswordSalt, '{');
if (false !== $saltBegins && $saltBegins + 1 <
strlen($mergedPasswordSalt)) {
$salt = substr($mergedPasswordSalt, $saltBegins + 1, -1);
$password = substr($mergedPasswordSalt, 0, $saltBegins);
}
return array($password, $salt);
}
