How to use md5 hash?

[Thekool1s]

I am planing to make a lotto but don't know how md5 works? Can any body explain it to me how it works? Suppose the jackpot numbers "10 25 1 31 22 8", I used this http://www.md5hashgenerator.com/ to generate the hash and the hash given was "175fb61c4ae79c9aaea9556a5511091d" How would my users know that i have not changed the result?

ur question is not specific enough, but if you make from this numbers md5 hash, its proof that this are the numbers, because if someone want check it and will make md5 hash from this numbers again, it always will give same hash

It is advisable to use SHA256 and above as they are easily crackable. You can also add random character behind your answer. For example, (1020305070)jahgsgsnd and hash it. Release it after the result have been announced.
