A startup named Ente, developing a service for confidential photo storage, has announced the launch of its server-side source code, in addition to the previously released client and mobile applications. The published code allows users to deploy their own photo storage and sharing service similar to Google Photos and Apple Photos. The server-side code is written in Go and is distributed under the AGPLv3 license. The client applications are written in TypeScript and Dart using Flutter and are prepared for Linux, Windows, macOS, iOS, and Android. A web interface is also available.
A distinctive feature of Ente is the ability to use end-to-end encryption to protect information in the event of storage compromise, allowing the use of untrustworthy providers without fear of data leaks. The cryptographic functions are built on top of the Sodium library. Algorithms such as Argon2 1.3 for hashing, X25519 for key exchange, XSalsa20 and XChaCha20 for encryption, and Poly1305 MAC for authentication are used. The cryptographic algorithms and source code used in the project have undergone independent audits conducted by Cure53 and Fallible.
The photo storage service supports selective access provision for individual images and the creation of shared albums that multiple users can access. Uploads to the storage can be done in the background. Import and export for different systems are supported. PostgreSQL is used as the database management system. To ensure storage reliability, information can be replicated across multiple independent storage units.
If desired, other types of data can be stored on top of Ente — the photo storage service is one of the application extensions. For example, the Ente Auth component can be used to create authentication apps similar to Authy, used for storing two-factor authentication codes and supporting code backup in the cloud and synchronization between different devices. Ente Auth and Ente Photos share the same server code.
