But if I take two very similar files, say two mkv (video) files with the same content, where only the headers differ, it's near impossible to see this with HxD, since I have to press F6 and hold it forever to get through the differing content before I finally get to the identical data. Unfortunately, it crashes when trying to compare files larger than ~100MB.
I also often do file comparisons and, as much as I love HxD, I prefer to use WinMerge whenever possible due to how it works in comparison. I agree 100% with this, and have been meaning to post something similar for a while. In my own use the side by side comparison aligned to the beginning of the file is by far the most important case, but probably everyone has different needs. Obviously there's a huge rabbit hole of diff tool stuff, I wasn't trying to request that HxD become the perfect diff tool. You'd have to be able to turn it off for that.anyway that's just an aside. Kind of at odds with the other requested thing, i.e. That's maybe a useful thing, being able to manually set the starting point for the comparison. you can set the current cursor position at two different locations in the different files before pressing F6. Yes, there's a lot of complicated stuff that diff/merge tools can do, but I was making this request because it seemed like it could have a lot more utility with hopefully relatively small feature additions.Īctually I notice that in its current form, it can be used to compare things that don't start at the same file offset, i.e. I don't want to hit F6 100 times in a row and then finally on the 100th time have it jump across the file to the next difference, I want to get to that next difference in one step. If there are 100 different bytes in a row that are different, that's one group. scrolling or using the cursor keys should scroll both panes at the same time (and probably a coloured highlight of the currently selected byte in both panels so you can see where you are).Ĭontiguous groups. I usually use a tool called VBinDiff for that task but having a comparison feature like this in a good windowed hex editor like this would be a much better replacement.Įdit: Realized F6 does the recentering for both compared files, but really when comparing groups you need to be able to move around in lock step to look, so there's maybe a little more to it:ģ. Without 1 this really can't be used to quickly visually inspect differences, and without 2 scanning for the next group of differences one takes too many presses of F6 to ever get there (imagine a 1000 byte string of changed data). Skipping to next/previous should go to the next contiguous group of changed bytes, not the next byte. When using comparison, highlight all differing bytes in view with some colour change.Ģ. I think it's very close to being extremely useful though, with only the following addition:ġ. Binary comparison is a task I do frequently and it would be great to have it integrated with a hex editor like this. However, the comparison feature does not seem useful at all in its current form. There are around 200 useful operations in CyberChef for anyone working on anything vaguely Internet-related, whether you just want to convert a timestamp to a different format, decompress gzipped data, create a SHA3 hash, or parse an X.509 certificate to find out who issued it.Have been trying out HxD recently, and I think it's a really fantastic hex editor. It is hoped that by releasing CyberChef through GitHub, contributions can be added which can be rolled out into future versions of the tool.

It should also appeal to the academic world and any individuals or companies involved in the analysis of digital data, be that software developers, analysts, mathematicians or casual puzzle solvers. It is expected that CyberChef will be useful for cybersecurity and antivirus companies. Simple functions can be combined to build up a "recipe", potentially resulting in complex analysis, which can be shared with other users and used with their input.įor those comfortable writing code, CyberChef is a quick and efficient way to prototype solutions to a problem which can then be scripted once proven to work. Complex techniques are now as trivial as drag-and-drop. The interface is designed with simplicity at its heart. CyberChef encourages both technical and non-technical people to explore data formats, encryption and compression.ĭigital data comes in all shapes, sizes and formats in the modern world – CyberChef helps to make sense of this data all on one easy-to-use platform.
