I found very good, powerful lotto generator made on cryptographic algo, called isaac+ on polish site about lotteries.

Using the form, you can generate numbersto play various lotteries. The mechanism is based on a cryptographically strong generator ISAAC [many proven advantages]. It is known that generators commonly found on other sites (based on the function "random" in php or javascript) are not suitable for Lotto games because they are not sufficiently initiated with random grain (using eg. the system clock). This generator is a pseudo ISAAC, with random grain size of 1,024 bytes downloaded from random noise of server system using MCRYPT_DEV_URANDOM, implemented in php.
