This is a very basic implementation of Rfc2898DeriveBytes class with only 2 of its constructors in
case someone else finds it useful.
class Rfc2898DeriveBytes
{
private $textToHash;
private $saltByteSize;
public $salt;
public function __construct($arg1, $arg2)
{
if (is_string($arg1) && is_integer($arg2)) {
$this->textToHash = $arg1;
$this->saltByteSize = $arg2;
$this->salt = substr(
hex2bin(sha1(uniqid('', true))),
0,
$this->saltByteSize
);
} elseif (is_string($arg1) && is_string($arg2)) {
$this->textToHash = $arg1;
$this->salt = $arg2;
}
}
public function getBytes($size)
{
return hash_pbkdf2(
"sha1",
$this->textToHash,
$this->salt,
1000,
$size,
true
);
}
}
