Finding matches in two files and outputting them

I want to use x[#] from first file and x[#] from second file, I want to see if those two values match, if they do I want to output those, along with several other x[#] values from the second file, which are on the same line.

The format the files are in :(but there is millions, and I want to find the pairs in the two files because they all should match up)

  line 1  data,data,data,data
  line 2  data,data,data,data

data from file 1:

 (N'068D556A1A665123A6DD2073A36C1CAF', N'A76EEAF6D310D4FD2F0BD610FAC02C04DFE6EB67',    
N'D7C970DFE09687F1732C568AE1CFF9235B2CBB3673EA98DAA8E4507CC8B9A881');

data from file 2:

The order it is sorted in is alphanumeric, and I want to use a slider method. By that I mean if file1[x] is < file2[x] move the slider down or up depending on whether one value is greater than the other, until a match is found, when and if so, print the output along with other values that will identify that hash.

What I want as a result would be:

file1[x] and its corresponding match on file2[x] outputted to a file, as well as other file1[x] where x can be any index from the line. values along with other values using an index method.

A starting point, add your own salt and pepper it's far from optimal and should use executemany etc...but that's for you to decide.
