Free encrypted secret sharing for everyone!
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.

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:latestAlternatively you can use docker-compose:
