Depending on your keyboard layout, the reach to this row of keys could be an uncomfortable trade-off compared to their functionality. ![]() Repurpose The Function Keysįor many of us, the function keys (F1–F12) end up completely unused. While I laid out a more detailed explanation for installing, setting up, and creating scripts using AutoHotKey in the aforementioned article, all you have to do is download the application, bring up a text editor, and save and run any of the following scripts to get them working immediately. If you are using straight obfuscation then you need not be concerned about this at all and you can in fact use obfuscation strings right up to the 253 character limit imposed by Autohotkey.Let me share with you five of the most useful AutoHotKey scripts for everyday PC use. In dynamic obfuscation, you don"t really want to go beyond 30 characters for obfuscation strings because security fragments will be inserted into them when calls to them are encoded, making them bigger. If you are using dynamic obfuscation instead of straight obfuscation and you set the Obfuscator to create large obfuscated object name strings, this will become more likely to happen. When it does, the program will complain on start up that some line number does not contain a recognized action. In some cases, however, an error of this type can still slip through to the code output by the Obfuscator. In most cases you will not even be aware that it happened because the Obfuscator is set to automatically roll back the insertion of the last security fragment that made it go over. Because Dynamic Obfuscator can insert multiple security fragments surrounded by percents into an obfuscated object name, the object name can sometimes exceed 253 characters. Using Single Letter Object Names Can Cause Invalid Obfuscator ReplacementsĪutohotkey limits variable names to 253 characters. ![]() I know, kinda ugly, but it is what it is right now. It would have to be a character that is legal as an Autohotkey variable including a-z, 0-9, or one of the legal special characters: So if the word total is being invalidly replaced, you could start it with an or an underscore : _total. This means that you add an extra character before or after the item that is being replaced in your text. The second workaround is to put a legal variable character before or after the word that is being invalidly replaced in your GUI text. If a variable name is an actual whole word and that word just happens to also be used a lot on your Gui interfaces, this option might require less work. The first workaround you can use is to change the name of the variable that is being invalidly replaced. I discussed how I think the Obfuscator should be modified in order to reduce this problem but first I will explain the workarounds to this problem you can use right now. This is most likely to happen in Gui, add statements and msgbox statements but it can also happen anyplace strings can be found including assignment statements, expressions, and passing literal strings to functions.Īt the current time there is no command in the Obfuscator to automatically fix this problem. For instance, you might use the word "total" in your GUI text and it could be a variable name as well causing invalid replacements of that word in GUI text. It can happen when the text in a control contains a word that is identical to some variable name that is being obfuscated in your program. This is an Obfuscator invalid replacement problem. A word like "total" found in the text of some GUI control might be replaced with a large string made up entirely of characters like When your user brings up that GUI window, it will show a very ugly obfuscated string on the interface! You can sometimes have the shocking problem where some of the words on the interface of a GUI box are replaced by an obfuscated string.
