in reply to un obfuscate logfiles with xor

Hmm, I don't quite understand you problem. If you file is encoded with a xor 255 (or a xor anything, for that matter), and if I understood your problem correctly, you should just need to apply the same xor to retrieve the original value.

Or did I understand you wrongly?

    Here is an example Óіߑёќߏ Thank you

      use strict; use warnings; my $s = q<Óіߑёќߏ +>; print pack "C*", map { $_ ^ 255 } unpack "C*", $s;
      <134> 2013/05/13 04-08-59 <> pf

      This only works if I run the code in an ASCII encoded file, there doesn't seem to be utf-8 involded here.

      unpack "C*", $s; returns a list consisting of the value of each byte in $s. pack with "C*" takes a list of bytes and turns it into a string. Read perlpacktut for more information on that.

      Is that an example of raw input, or the output from the current iteration of your script? It would be helpful to know we have a clean fragment of raw logfile data

[Corion]: We-ird - I hadn't known this, but Ingress and Pokemon Go (both AR games in the real world where you run around) switched from using Google Maps to OpenStreetMaps, which is great. But I wonder why, as Ingress is (was?) owned by Google/Alphabet. But ...
[Corion]: ... maybe not wholly owned, or the load on Google Maps was too high?!
