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. Additional guide.
2. Set up APP_HOST environment variable:

# Windows
set APP_HOST=<url>
# Linux
export APP_HOST=<url>
# 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.
