# Death Code
|
||||||
|
|
||||||
|
Death Code is an entirely self-hosted web application that utilizes [Sharmir's Secret Sharing](https://en.wikipedia.org/wiki/Shamir%27s_Secret_Sharing) to share secrets after you die. After splitting a secret among a group of people, the secret can only be reconstructed when a sufficient number of people combine their parts together, presumably only after you are gone from this earth.
|
||||||
|
|
||||||
|
## Building
|
||||||
|
|
||||||
|
1. Install `git`, `docker`, and `docker-compose`
|
||||||
|
2.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git clone https://github.com/andrewkdinh/death-code.git
|
||||||
|
cd death-code
|
||||||
|
cp .env.example .env
|
||||||
|
# Edit .env
|
||||||
|
git clone https://github.com/daniel-e/rust-captcha.git rust-captcha
|
||||||
|
docker-compose up -d
|
||||||
|
```
|
||||||
|
|
||||||
