Autohotkey read binary file

If the data is not UTF text, this conversion generally changes the data in undesired ways. Finally, FileOpen and File. RawRead or File. Read Num may be used to read binary data without first reading the entire file into memory. When the goal is to load all or a large part of a file into memory, FileRead performs much better than using a file-reading loop.

If there is concern about using too much memory, check the file size beforehand with FileGetSize. Yes, VarSetCapacity was the problem, i solved that. The only thing that boders me is BinWrite process speed. I was thinking if there is a way not to read the rest of the file, but only inject the encrypted part, something like editing. Can this script do the job? PhiLho's Binary file reading and writing. For large files you should use the Windows built-in AES encryption. Encryption is not a problem it is done quickly, but after that BinWrite process is slow.

I didn't use conversion to hex, BinRead returns binary right? All i did was read binary, encrypt, and write binary. The functions here handle the data as hex bytes, therefore they are slow for large files. So you are saying that i need to convert to binary and then write the file?

If this is binary file ,and i want to ADD 11 into file, if i want to write at begining offset has to be 0, what if i want to write somewhere in the midle or at the end? For example:. Zero or more of the following strings. Separate each option from the next with a single space or tab. Encoding : Specify any of the encoding names accepted by FileEncoding excluding the empty string to use that encoding if the file lacks a UTF-8 or UTF byte order mark.

This option overrides any previously specified encoding and vice versa. If Text is not an object, the data size is always a multiple of 2 bytes due to the use of UTF strings. This translation typically does not affect performance.

Several attackers involving living-off-the-land methods have made headlines in recent years. For example, a threat actor known as Gallmaker used the Microsoft Office Dynamic Data Exchange protocol back in to spy on its victims. A year later, attackers misused the Windows Management Instrumentation Command tool to distribute Astaroth.

This is a Microsoft product, an open-source scripting language designed for machines running Microsoft Windows. AutoHotkey scripts can automate repetitive tasks in a Windows app by creating macros, shortcuts or hotkeys. One of the first publicly reported attacks involving AutoHotkey was a credential stealer written in AutoHotkey found in March The threat, dubbed Fauxpersky, dropped four files into the affected environment.
