scrypt VS react-dropzone

Check out the scrypt encryption tool.

Given that the encryption algorithm is open source (https://github.com/Tarsnap/scrypt) can you try to explain what you mean here?

I wouldn't use OpenSSL personally. If you just need simple but secure symmetric encryption, checkout the scrypt(1) encryption utility from Tarsnap. If you need support for public keys, check out age(1).

scrypt if you strictly only need symmetric encryption.

First of all I know that "implementing your own cryptography is bad". However, at some point, one does stumble upon a use-case that is not (well) covered by existing tools.

Now, assuming one has already done his due-diligence and has read (and hopefully understood at least the main ideas of) cryptography related articles / posts / etc. (especially in the area pertaining to what one wants to build), and thus we can assume one is not a complete newbie in this mater, however, nor is he an expert. Basically we can assume he is an "amateur".

Where would one go with his design to ask for feedback about it, in the hope to at least eliminate some weaknesses that one (as a non expert) might have overlooked. (I'm not speaking here about "proofs" or "audits".)

----

More specifically ---- but please let's not get into this right now, this being just an example ---- I'm trying to implement something similar to `scrypt` (the encryption utility, that uses the `scrypt` PBKDF, ) or `age` (), as a replacement to my current solution that relies on GnuPG.

It entirely does and that's exactly my point. Most "hashes" are designed to be fast, for data validation/checking whatever. For securing data (passwords, anonymisation, etc) you want a "hash" to be as slow as possible. Scrypt for example is designed to be extremely slow and use much memory (making GPU-based parallelisation useless and driving up the cost of CPU-based work). The default settings for five-second hashes changes their 18 hour estimate to a bit over two years... and that's assuming you don't turn it up further.

6. Simplify File Uploads with React-Dropzone

Website: React Dropzone

In addition to being able to access the file browser to select an image to upload, I also wanted to be able to drag'n'drop that image as well. While researching a few options, I came across react-dropzone, a "Simple React hook to create a HTML5-compliant drag'n'drop zone for files." Installation was easy, and the docs were well-written with many examples of different applications.

The journey starts with the user uploading the PDF document. For this, I used the react-dropzone library. The library supports both drag-and-drop and click-based uploads. Once the user drops the file into the input, the file is sent to the backend for processing

React Dropzone is a popular open-source library for creating file upload components in React applications. It provides an easy way to implement drag-and-drop file uploads and supports various customization options.

If you want some more advanced functionality, take a look at react-dropzone

4. React Dropzone

React-dropzone react-dropzone is a set of React libraries that help developers to build complex drag-and-drop functionalities while keeping their components destructured. In other words, it is a React hook that makes it easy to construct drag-and-drop interfaces quickly rather than from scratch.

In this React tutorial, I will show you way to build Drag and Drop File Upload example with React Hooks using react-dropzone, Axios and Multipart File for making HTTP requests, Bootstrap for progress bar and display list of files' information (with download url).
