> ONLY USE THIS TOOL OFFLINE

## About

This tool aims to be an easy to use tool for securing your crypto (seeds / recovery phrases / mnemonics) via Shamir Secret Sharing, implementing [slip39](https://github.com/satoshilabs/slips/blob/master/slip-0039.md) from Trezor creators, Satoshi Labs.

The tool supports:
- Easy recovery phrase generation
- Easy share generation and restoration
- Group based share generation with variable thresholds from SLIP39
- Multi-language recovery phrase generation
- BIP32 info
- BIP39 seed shortening
- [Cryptosteel Capsules](https://cryptosteel.com/product/cryptosteel-capsule/?v=3a52f3c22ed6)

## Online Site (GH-PAGES)

- ~~[seedhodler online](https://seedhodler.github.io/seedhodler/)~~ - There is currently no online site for the beta version. Please use docker instead.

## Build Static Site Setup

```bash
# install dependencies
$ yarn install

# serve with hot reload at localhost:3000
$ yarn dev

# build for production and launch server
$ yarn build
$ yarn start

# generate static site
$ yarn generate
```

# Running standalone with Docker

Prerequisites:
 - docker

Using docker:
- build docker image: `$ docker build -t seedhodler:local-build . `
- run container: `$ docker run -it -p 4000:4000 seedhodler:local-build`

Using docker-compose:
- build image: `$ docker-compose build seedhodler`
- run container: `$ docker-compose up`

# Docker + Offline Machine standalone runner

You can run the seedhodler tool in docker in your offline/cold storage machine that has docker installed.

- online-machine:
    - build the image: `$ docker build -t seedhodler:local-build . `
    - save the image: `$ docker save seedhodler:local-build`
    - copy the zip file to another machine e.g. your offline/cold storage machine 
- offline-machine (with docker):
    - copy the `seedhodler.zip` file
    - cd into the same directory
    - load image: `$ docker load -i seedhodler.zip`
    - run container: `$ docker run -it -p 4000:4000 seedhodler:local-build`
