Well you get the award for the one liner solution.

The reason I didn't start with 1000000 is because the pin in theory could have beginning with a 0.

Only a few lines of code dude Hardly worth commenting.

Would be nice to know a few things in English.

For example. you have a loop with a variable 0 which incs each time the loops is ran. the md5 function is hashing the variable? and checking it against an char?? Might help us beginners.

With mine, I created a wordlist which looked like this:

0000000, 0000001, 0000002, 0000003.........etc 9999998, 99999999.

So I load the wordlist which contains this into a variable called $data. I then use the explode() function to create an array of all of the numbers, i separated them with the comma.

$word = explode(",", $data);

So if I am looping - on the first iteration..

$word[0] = "00000000"
$md5 = md5($word[$i])
$md5 will equal "dd4b21e9ef71e1291183a46b913ae6f2"


I then check if the substring of the MD5 matches what Damo wants:

My first substring is: substr($md5,30,2) = "f2"

It doesn't match what Damo wants, so it skips back to the start of the loop - it keeps doing this until my MD5 substring is equal to "5a". When it is, it will then check the SHA1 substring to see if it matches... Etc...

It goes on and does this until all 3 substrings of the 3 hash values of whatever digits we are on will match what Damo requires which is:

MD5 substring will be: 5a
SHA1 substring will be: f1
SHA256 substring will be: 91

That's very nice of you to post a very detailed analysis into what your code is doing.

$word[0] = "00000000" is this

is this just 4 bytes?00000000

No, sorry - that is supposed to be 7 0's.
