About this project
Encrypted secret sharing for everyone!
Hemmelig is a encrypted sharing platform that enables secure transmission of sensitive information. All encryption occurs client-side using TweetNaCl, ensuring your data remains encrypted before it reaches our servers. The platform supports both personal and organizational use cases, with features like IP restrictions, expiration controls, and optional password protection. Whether you're sharing credentials, sensitive messages, or confidential files, Hemmelig strives to ensure your data remains private and secure.
- Visit https://hemmelig.app and enter your sensitive information
- Configure your secret:
- Set expiration time
- Add optional password
- Set view limits or IP restrictions
- Click "Create secret link" to generate a secure URL
- Share the generated link with your recipient
The security model works by:
- Generating a unique encryption key for each secret
- Performing all encryption in your browser before sending to the server
- Including the decryption key only in the URL fragment (never stored on server)
- Server only stores the encrypted data, never the plain text or keys
Example encryption flow:
encryptedData = encrypt(yourSecretData, uniqueEncryptionKey)
// Only encryptedData is sent to server
// uniqueEncryptionKey is only shared via URL as a fragment.
