ending numbers ignored on ftp password

[sci2tech]

I`d like to propose a better solution for function generate_rand_salt

Code:

function generate_rand_salt($min = 46, $max = 126) {
    if (CRYPT_BLOWFISH == 1) {
        $length=13;
        $pre='$2$';
    } elseif (CRYPT_MD5 == 1) {
        $length=9;
        $pre='$1$';
    } elseif (CRYPT_EXT_DES == 1) {
        $length=9;
        $pre='';
    } elseif (CRYPT_STD_DES == 1) {
        $length=2;
        $pre='';
    }
    $salt=$pre;
    for($i=0;$i<$length;$i++)
        $salt .= chr(mt_rand($min, $max));
    return $salt;
}

Also restore function to crypt_user_ftp_pass

Code:

function crypt_user_ftp_pass($data) {
    $res = crypt($data, generate_rand_salt());
    return $res;
}
