The existing HTML gadget only encodes a fixed set of HTML entities. It should have options for things like using named entities vs numbered entities, whether to encode only reserved characters or all characters, etc.

The project has a SHA2 gadget but it is fixed at 256 bit digests. There should be an option to select digest size: 224, 256, 384, or 512.

This would be great for DX. The Svelte FAQ says:

How do I do hot module reloading? permalink
We recommend using SvelteKit, which supports HMR out of the box and is built on top of Vite
and svelte-hmr. There are also community plugins for rollup and webpack.

The rollup link is: https://github.com/rixo/rollup-plugin-svelte-hot

Describe the use case:

A common scenario when vulnerability hunting or reverse engineering is to come across some opaque string that you want to modify. So you may need to decode the string first (which may take multiple steps), then you want to edit the string, and then re-encode it (going through the same steps in reverse). It possible to set up a chain of steps that go through decoding and then re-encoding, but there is currently no way to edit a value in the middle of a transformation change.

Describe the solution you'd like to see:

A special type of input gadget that has an input port and a "latch" button. A user can edit the buffer at will. When the latch button is clicked, the data on the input port button overwrites the input's edit buffer.

Describe the alternatives:

The way I work around this right now is by creating two inputs and copy/pasting from the last decode step into the second input. The "latch" gadget would just be an elegant way to copy/paste into an input gadget.

Summary:

On Safari, dragging out a new wire doesn't highlight the target port. It seems like Safari doesn't fire the :hover CSS pseudoselector when the mouse button is down?

I was wondering if this project has been abandoned because it is very interesting and has potential but I have seen that there have not been any commits on this.

this seems very similar to cyberchef or my text format wizard, but a graphical version, which intrigues me.

Similar to #17, maybe a precursor: specify static, pre-built assemblies that can be loaded based on URL hash. For example, hxxps://encoding.tools/#base64-decoder would load an input gadget and a base64 decoder gadget into the workspace and pipe them together.

I originally wrote this using bare DOM since Angular was wayyyy overkill, but there are some funky issues resulting from my half-baked DOM wrapper. Consider switching to VueJS or SvelteJS.

Edges are straight lines and kind of ungainly. D3 has code for drawing bezier paths. http://using-d3js.com/05_01_paths.html

Let's say we have the following gadgets: input → hex decode → url encode. In the input field we type 706172616d3d666f6f. Then the hex decoder will show param=foo. Then URL encoder will show param%3Dfoo. Maybe you wonder where did %3D come from, so you highlight those three characters.

Right now, the other gadgets won't do anything, but it would be pretty cool if they could highlight the corresponding parts of their data. E.g. the hex decoder would highlight =, and the input gadget would highlight 3d.

The application has zero support for touch screens. It probably wouldn't be very useful on phones and other small screens, but I could see this being usable on tablets. Should we add support for touchscreen devices?

It might be nice to be able to save an assembly (i.e. a collection of gadgets that a user has wired together) and be able to load it later. Of course we don't keep any server-side state, so it would need to be saved somewhere else, either HTML5 local storage or maybe something like a github gist?

Once saved, could the assemblies be shared with other users? Maybe by pointing to the gist ID? Or encoding the entire assembly into a URL parameter?

Invalid inputs (such as an odd number of input characters to the hex decoder) are not reported to the user. The gadget with the error just says "null".

Error messages need to be displayed to the user instead of being silently swallowed, and need to decide how subsequent outputs are handled. If there's an error in the hex decode, for example, should downstream components keep the same state, switch to null, or display some other error?

Most of the gadgets have a lot of duplicated code and really only a few lines of unique implementation (e.g. MD5 and SHA1 gadgets differ by only a few lines of code)., This is a result of trying to get this project done on a short timeline. It would be faster and easier to create new gadgets if the duplicated code was factored out.
