The crypto-helper is a web app that helps to work with the different crypto algorithms. This app can hash/hmac, encrypt/decrypt, and sign/verify the data, debug JWT tokens, parse ASN1 structures, compute diffs, and more.

All computations are performed on the client side. _This tool never sends the data to any server._

### Development

0. Install WebAssembly target: `rustup target add wasm32-unknown-unknown`.

1. Install [`trunk`](https://github.com/thedodd/trunk). [Additional guide](https://yew.rs/docs/next/getting-started/introduction#install-trunk).

2. Set up `APP_HOST` environment variable:

```bash

# Windows

set APP_HOST=

# Linux

export APP_HOST=

# example:

# export APP_HOST=https://crypto-helper.qkation.com

```

This env variable is used for the url generation when you click the *share by url* button.

3. Run `trunk serve` in your terminal.

4. Go to http://127.0.0.1:8080 in your browser.
