SaaS

Hemmelig is available at https://hemmelig.app

How it works

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.

Features

• Self-hosted version. Keywords: Regulatory compliance

Self-hosting

If you have to follow some sort of compliance, and have to self-host, https://hemmelig.app is available as a docker image. The following is the bare minimum to run the docker image.

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

docker run -p 3000:3000 -d --name=hemmelig \
    -e SECRET_REDIS_HOST=127.0.0.1 \
    -v /var/tmp/hemmelig:/var/tmp/hemmelig/upload/files # this is how you mount a local directory if you choose to use disk upload, and not do/s3
    hemmeligapp/hemmelig:latest

Alternatively you can use docker-compose:

# fetch docker-compose.yml
wget https://raw.githubusercontent.com/HemmeligOrg/Hemmelig.app/main/docker-compose.yml

# start hemmelig & redis
docker-compose up -d

# stop containers
docker-compose down
