Seems like you might want to try AutoHotkey_H first Unfortunately I can't do this as I've already written 40,000+ lines in AHK_L. I'm even locked into using v1.1.24.03 as I can't trust later versions won't break something. AutoHotkey_H is a superset of AHK_L. So your script for _L should work fine ...

Seems like you might want to try AutoHotkey_H first you might want to write it directly in C/C++, Object Pascal, Rust, Go, etc... Unfortunately I can't do this as I've already written 40,000+ lines in AHK_L. I'm even locked into using v1.1.24.03 as I can't trust later versions won't break something...

Here is how I imagine a solution might work: 1. Encrypt your .ahk file using jNizM's CNG API . 2. In ahk's script.cpp , rewrite OpenIncludedFile() to decrypt your script, eg: ts.Open(textbuf, TextStream::READ | TextStream::EOL_CRLF | TextStream::EOL_ORPHAN_CR, CP_UTF8); Replace with: ts.Open(Decrypt...

The lib uses bcrypt.dll and not advapi32.dll

Sorry my mistake. For some reason I'm still using your older HashCalc library for the hashing and your new CNG for the encrypting. Not sure why I ended up doing it that way tbh

pneumatic

Why you dont sign your exe with a certificate? Thanks for the suggestion, and I might do that anyway, but I've since come across that tool (I won't link it) which decompresses the >AHK WITH ICON< resource, which makes it too easy to exploit, so I'm now rethinking the whole thing. Other solutions I'...

Aha, this one works

Code: Select all

If ("" . string1 = "" . string2)
msgbox true

I want to compare two strings but ahk keeps interpreting them as numbers which has a 19 digit limit. For integers, 64-bit signed values are supported, which range from -9223372036854775808 (-0x8000000000000000) to 9223372036854775807 ;19 digits string1 := "14887102821589797144" ;20 digits string2 :=...

If you want to protect the source code google "ahk obfuscation" Yeah I looked into that some time ago and came to the conclusion that it was a bit questionable in terms of reliability as I read some posts about how it couldn't correctly handle certain syntax or caused bugs in the app. I think I'm o...

And now I'm starting to see why you are right - performing mathematical operations can result in a loss of precision which makes the hash no longer unique

pneumatic

Then I use bit shift left : MsgBox, % StrLen("abcd") "`n" StrLen("abcd") << 1 So in unicode ahk, strings are twice as large, therefore loop twice as much. Now I get it :) MsgBox, % !!A_IsUnicode ; if unicode — 1, else 0 But why the double NOTs? edit: ah because it could be blank. Thought it would b...

pneumatic

Thanks, and that seems to do the same as Asc(), except you are converting it to a hex whereas Asc() converts it to decimal. But I'm not sure the ordering is right because Asc() produces "97 98 99" for "a b c" whereas your algorithm reverses the order ("99 98 97" in decimal, or "63 62 61" in hex) Sin...

pneumatic

I think Asc() might do the trick. It won't be the string's binary data interpreted as an integer [edit: it seems that it actually is], but it will be a unique integer for each character in the string, which is all I really need to allow performing maths on it.

pneumatic

Damn, so what is the number retrieved by NumGet()? It does change for certain strings (long ones vs short ones) just not the strings you happened to specify. But it doesn't change enough to provide security.

Similar thing with MsgBox, % Format( "{1:i}" , "3bea1dd4dec09f279d24ccea3c138735" )

pneumatic

For fun, here's how my system would work. Criticism encouraged! 1. Compile and MPRESS the script to an exe 2. Generate hash of exe and convert to number with NumGet() 3. "Encrypt" the number by performing some arbitrary convoluted maths on the number 4. Store result of (3) on disk somewhere, prefera...

pneumatic

I just realised, I don't need to convert it back to a string when I could just compare the result of NumGet() to a copy stored on disk.

But I'm still curious to know if there is a way to convert a var's binary data to a string.

I always just append the number to a blank string:
Code: Select all
number := 8
str := "" number
msgbox, % str
; => "8"

But I want to convert its binary data back to Unicode characters.

I think this does the same as your example

Code: Select all

string := Format( "{1:s}" , 123)
msgbox % string

pneumatic

don't But I don't trust the algorithms in crypt32.dll, bcrypt.dll, msvcrt.dll to produce the same output on all Windows systems. I'd rather just write my own simple encryption, like just multiplying the string (which is a hash of my app's exe) by, say, my birthdate and then divide by some other num...

pneumatic

I'm trying to implement my own [very basic] encryption algorithm to perform mathematical operations on a string. My idea is to convert the string to a number first, then perform maths on that number, before converting it back to string. string1 := "string" string2 := NumGet(string1) ;convert string ...

pneumatic , Every implementation of a given hash function (say, SHA256) must give the same hash, under any OS, under any circumstance. If it does not, the implementation is faulty. Yes, that does make sense. I guess one other worry I have is that different versions of that dll might use different f...

pneumatic

Since the library uses advapi32.dll to generate hashes, I am worried that maybe different Windows systems will have different versions of advapi32.dll in their System32 folder, which might use slightly different implementation, causing a different hash to be generated, which would break my entire ap...
