The original Hemmelig app is available at https://hemmelig.app

You enter https://hemmelig.app, write your sensitive information, expire time, optional password, and click create a secret link. You share the secret link. The receiver of the link opens it, writes the optional password, and retrieves the sensitive information. When a secret link is created, it gets its unique encryption key that is not saved to the database and only will be part of the URL. This is how the encryption works: encrypt(DATA, YOUR_UNIQUE_ENCRYPTION_KEY). The encryption of the text and files is done in the client; this means the server will get the encrypted information, and nothing in clear text.

This build uses https://github.com/fastify/fastify-oauth2 to handle authentication with all the original signup and signin ability removed. If you enable users, you will need to define the SSO Environment variables.

NOTE: I built this in half a day, I can not vouch for this codebase's security. I have made every effort to ensure it is safe and secure but am no expert. If you find an issue please do feel free to submit a pull request!

# To use this image you need a redis database enabled.
# Example:
#
# $ docker run -p 6379:6379 --name some-redis -d redis
#

You can use [docker-compose](https://docs.docker.com/compose/):

```bash
# get the repo
git clone https://github.com/calw20/Hemmelig.app.git
cd Hemmelig.app

# edit docker-compose.yml to add your SSO details
vi docker-compose.yml

# start hemmelig & redis
docker-compose up -d

# stop container
docker-compose down

Have a look at the Dockerfile for a full example of how to run this application.

Hemmelig can be used as a CLI to create secrets on the fly

# Pipe data to hemmelig
cat mysecretfile | npx hemmelig

# For the documentaiton
npx hemmelig --help

Have a look at the public/locales/ folder.

# First you have to run redis
# Example by using docker
docker run -itd -p 6379:6379 redis

npm install

# Start the frontend/backend
npm run dev
# http://0.0.0.0:3000
