deobfuscation

I am working on a software program that has to be deployed on private cloud server of a client, who has root access. I can communicate with the software through a secure port. I want to prevent client from reverse engineering my program, or at least make it "hard enough". Below is my approach: Write code in Go and compile the software into binary code (may be with obfuscation) Make sure that program can only be initiated with secret key that can be sent through the secure port. The secret key can be changing depending on time. Every time I need to start/stop the program, I can send commands

I need a subroutine that, given a set of characters, will generate all possible combinations of those characters of length k. Order matters and reuse is allowed, so if k = 2 then AB != BA and AA is an option. I found some working examples on PerlMonks , but unfortunately they are code golf and not easy for me to wrap my mind around. Can someone please do one or more of the following? Give a breakdown and explanation of how the first algorithm works. De-obfuscate the code so that the meaning is clearer. Point me toward another example that is clearer. Thanks! cjm You can use variations_with

Error Message: Upload missing dSYMs to see crashes from 1 versions. Versions affected: 1.0 (1) I am trying to implement Firebase Crashlytics in my iOS project. I did all the setups according to Firebase Crashlytics Doucmentation . The crash is performed manually when the button is clicked just to see whether the crashlytics is working. @IBAction func onTestCrashButtonClick(_ sender: UIButton) { Crashlytics.sharedInstance().crash() } But when i tried to see the error report in the firebase console, it shows something like this image. After reading Get Deobfuscated crash reports I just Set Debug

I received a spam email that contained an attachment with a .js file, and out of curiosity I opened it up in notepad (didn't run it of course). Had to disable ESET temporarily as it was marking this as a trojan. I was wondering what this actually does: autonomousRadio = eval(('transport', 'caste', 'acoustic', 'primitive', 'absurd', 'clip', '\u0074phenomenon'.e()) + 'h' + ('station', '\u0069program(me)'.e()) + 's'); autonomousRadio = autonomousRadio[('barbarian', '\u0041ruin'.e()) + 'ct' + ('state', 'prologue', 'accompany', 'orientation', 'chance', 'unison', '\u0069cyclone'.e()) + 've' + (

I've got some code that was at the bottom of a php file that is in javascript. It goes through lots of weird contortions like converting hex to ascii then doing regex replacements, executing code and so on... Is there any way to find out what it's executing before it actually does it? The code is here: http://pastebin.ca/1303597 You can just go through it stage by stage - since it's Javascript, and it's interpreted, it needs to be its own decryptor. If you have access to a command-line Javascript interpreter (such as the Console in Firebug ), this will be fairly straightforward. I'll have a
