MyBB password hash - kristo - 20.10.2013

I'm trying to make a MyBB hash generator but it keeps giving me wrong hashes and cancers.

My function:

pawn Код:

stock HashMyBBPassword(string[], salt[])
{
    new string2[48];
    format(string2, sizeof(string2), "%s%s", MD5_Hash(salt), string);
    string2 = MD5_Hash(string2);
    return string2;
}

Original function (PHP):

PHP код:



function salt_password($password, $salt)

{

    return md5(md5($salt).$password);

}

What am I doing wrong?

Still waiting for help.

MyBB code:

PHP код:



function generate_salt()
{
    return random_str(8);
}
function salt_password($password, $salt)
{
    return md5(md5($salt).$password);
}

$pass = $mybb->input['password'];

$md5pass = md5($pass);
$salt = generate_salt();

$salted_pass = salt_password($md5pass, $salt);

As you can see, $md5pass, which contains a MD5 hash, gets passed to the function salt_password.

So there's your mistake.

Oh, didn't see that part. I'll test it, thanks.

Also thanks to Smally.

Idk... I'm still getting wrong hashes.

pawn Код:

stock HashMyBBPassword(string[], salt[])
{
    new string2[96];
    format(string2, sizeof(string2), "%s%s", MD5_Hash(salt), MD5_Hash(string));
    string2 = MD5_Hash(string2);
    return string2;
}

Bump.

Re: MyBB password hash - rickisme - 20.10.2013

problem is MD5_Hash always return a upper string (:

check this code to see what's different:

pawn Код:

// old hash
stock HashMyBBPassword(string[], salt[])
{
    new string2[96];
    format(string2, sizeof(string2), "%s%s", MD5_Hash(salt), MD5_Hash(string));
    string2 = MD5_Hash(string2);
    return string2;
}

//new hash
stock HashMyBBPassword2(string[], salt[])
{
    new string2[96];
    format(string2, sizeof(string2), "%s%s", MD5_Hash(salt), MD5_Hash(string));
    for(new i=0; i < sizeof(string2); i++)
    {
        string2[i] = tolower(string2[i]);
    }
    string2 = MD5_Hash(string2);
    return string2;
}

public OnGameModeInit()
{
    new string[128];
    format(string, sizeof(string), "%s", HashMyBBPassword("password", "salt"));
    printf("old hash : %s", string);
    format(string, sizeof(string), "%s", HashMyBBPassword2("password", "salt"));
    printf("new hash : %s", string);
    return 1;
}

YEAH! Working, repping you asap. I didn't think about case.
