I know MD5’s safety is under question lately and this is the reason a lot of people are using salt (I dont understand this at all btw) but I was wondering if you wanted to easily implement a safe system in php can you just md5 something twice?

like test > 098f6bcd4621d373cade4e832627b4f6 > fb469d7ef430b0baf0cab6c436e70375

So basically:

$val = 'test';
$val = md5($val);
$val = md5($val);

Would that solve the whole rainbow security stuff? Is there an easy/noob proof way of making secure database passwords in php?

    If you don’t believe in MD5, you can try a higher algorithm by using the hash() function:

    $hash1 = hash('sha1', 'The string to hash by SHA-1');
$hash2 = hash('sha256', 'The string to hash by SHA-256');
$hash3 = hash('sha512', 'The string to hash by SHA-512');
$hash4 = hash('ripemd160', 'The string to hash by RIPEMD-160');

    In my opinion it does not make sense to hash twice.

    EDIT: Fixed typo in last line of code.
