Re: HxD code that it do not currupt exe

You need to uncompress it first, modify it, then recompress it to ensure the compressed data remains valid. As far as I remember UPX offers options to uncompress as well.

Changing compressed data in place while ensuring it remains valid is close to impossible.

Re: Feature: Add Half (float16) to data inspector

Will not be easy (since I need to make a special decoder for float16 to string values and back -- this doesn't come by default in most languages). But should be well documented and useful. P.S.: What would you need it for? I mostly know of float16 being used in deep learning, but I don't see why you...

Let me know if you are interested in this plugin approach, as mentioned in my last mail.

Re: DataInspector: provide some Varint decoding for Git

From previous email exchange: It could be added to the data inspector. The basic unsigned format seems reasonably simple, the more compact ones less. I found this article https://en.wikipedia.org/wiki/Variable-length_quantity which also describes the Git encoding. However it is slightly confusing an...

Re: Deterministic RNG

Note for future implementation: Another thing that will have to change, is that currently the passes are done only in memory It is comforting that one pass is probably enough. But with high degree of chaotic randomness. The "wipe securely" function under tools/extras will use several passes (if you...

Re: Deterministic RNG

Note for future implementation: Another thing that will have to change, is that currently the passes are done only in memory (except if you chose wipe file). This allows for undo, but defeats the purpose of multi-pass wiping a portion of the file/disk, for example. So a direct mode would be necessar...

Datainspector: byte $C0 in Int8 row (in hexadecimal number mode) should not display as ffffffc0

Instead it should display as C0, the same way as UInt8. This is due to converting it to a signed Int8 that is then passed on to a (U)Int32 or an (U)Int64, at which point a sign extension happens, which show as leading F's. Also look how others handle this, as usually hexadecimals are always positive...

Offset casing is not updated in data inspector and status bar, after changing options

When changing the casing for hexadecimal offsets or numbers in the options dialog, the TXmHexEdit ist updated, but not the data inspector, and not the status bar. Should watch/subscribe to an update event (that watches this specific option change), and then refresh the display of statusbar/data insp...

Re: Deterministic RNG

Thanks for the link of this nice compact code.
From what I can tell it is only for floating points numbers, though. I am not sure how well the guarantees transfer to integers.

Re: Checksum calculation feature visibility problem

It came from a resize while designing that went unnoticed, since the settings where different in the local INI file. Thanks for reporting.

Fixed in the development version.

Re: Vertical bar on the right side of HxD's window

Maybe it's some kind of tool or driver issue?

Re: unicode two bytes chars, how can I enter ?

Thanks, for your feedback. As can be seen in both neo and wxmedit, UTF-8 support is hacked into the grid based UI, adding spaces after characters that are encoded as two or more bytes, which makes it hard to distinguish between actual spaces and filler spaces. Especially when a character is made up ...

Re: Deterministic RNG

Hi, I deleted your other post in support, since it was a duplicate. For a truly (or at least cryptographically secure) random number generator this probably wont suffice. Do you want to wipe data or what is the purpose of this change? Because in this case, there might be other points to keep in mind...

Re: Data inspector: Navigation to next or previous element of same type

Implemented a toolbar in the data inspector in the current development version, similar to the navigator for the disk (image) editor. Possibly add another toolbar under the main menu, for setting the byte offset directly using a spin edit and incrementing/decrementing the offset in byte steps. This ...
