Smart Hex editor, preferably free?

Question

hex

It is necessary to parse some binary file of non-trivial structure. I have a complete manual for the file device, it remains only to choose a good tool. OS is preferably Win, but any will do.
We need a Hex editor that will be able to highlight certain patterns and offsets during editing. The difficulty is that structures such as 2 bytes are often found, of which 10 bits are the label naming, 6 are the label parameter. Those. you need to highlight such bit combinations ranging in size from a nibble to several bytes.
I tried the plugin for notepad++, Hex Editor Neo, and a bunch more. Of the free ones with highlighting, I didn’t find anything at all. Hex Editor Neo patterns are only multiples of a byte. In ubuntu in the installer I looked at everything in hex, nothing highlighting can do at all.
UPD: And unicode support in string representation is very useful

Answer 1

HxD - I recommend, free, fast, opens large files, disk editor.

Answer 2

winhex in my opinion is fine, but it is shareware

Answer 3

There is also 010 Editor , unfortunately, paid, but it seems to be specially sharpened for parsing structures. I myself have not tried it yet (hands have not reached), so I can not say anything.

Answer 4

IDA + script to it? :-)

Answer 5

Look towards okteta. There is definitely support for parsing the structure of elf files, but I don’t know about others

Answer 6

In order not to suffer with the search, Wikipedia.org has a huge table comparing a large number of HEX editors. Based on it, the most sophisticated editor is “HHD Software Hex Editor Neo”.

Answer 7

Everything depends on the tasks. 010Editor, for example, is ideal for analyzing foreign formats due to intelligent scripts and templates (the rest are smoking aside). WinHEX is versatile and fully functional. Hiew is cute, light and positive + diasm.
For your task, definitely 010Editor, believe me.
