Projects that use Themis #

Themis is widely-used for both non-commercial and commercial projects. We’ve mentioned some of the public projects in a blog post in December 2018, and a more complete list is as follows (in alphabetical order):

AppSpector — remote debugging platform for iOS and Android apps. Themis is used for end-to-end encryption of stored and transferred session data.
Bear App — endorsed by Apple iOS note-taking app. Read more about how we’ve helped to add end-to-end encryption of user notes in this blog post: Implementing End-to-End encryption in Bear App.
GoClinic — healthcare information exchange platform from the Netherlands created for safe, effective, expedient, and long-term successful treatment of hospital patients. Special thank you goes to @popaaaandrei.
Gochat by @ys1382 — open source secure chat written in Go which uses Themis as the encryption engine. If you want to improve your Go knowledge – consider reading the source code.
Hashblock-exchange — Hyperledger Sawtooth-based blockchain application where Themis is used to encrypt transaction content in blocks with elliptic cryptography.
kit — personal organiser mobile app for iOS and Android for secure storage of logins, passwords, dates, and notes with the help of end-to-end encryption. Themis is used to encrypt all the data that is shared between the users.
Media-sharing project that allows users to earn money by sharing media content. Themis is used as a multi-platform library for iOS, Android, and PHP sides of the project.
Virtual data room app — Themis is used for storage encryption of user’s PII, credentials, API keys.

Libraries #

Themis is used as dependency of other libraries:

Android secure storage library by EPAM is written on Java and allows storing encrypted values in Secure Preferences (supports Themis and Cipher encryption providers).
AndroidSecurePreferences by @genaku, with data encryption based on Themis.

Sample projects #

During the development stage, we frequently do Proof-of-Concept projects to test different assumptions.They serve as interesting demos (examples) of what Themis is capable of:

0fc — anonymous web chat. Python + WebThemis (C++, HTML/JS). Read the blog post.
Sesto — secure storage. Python + WebThemis (C++, HTML/JS). Read the blog post.
Swift Alps — secure communication demo: an iOS app with Python server based on Secure Session. Swift + Python. Read the blog post.
Zero-Knowledge Architectures workshop — iOS app for storing and sharing encrypted notes stored in Firebase database. Swift.
Java and Android examples — a set of handy examples that show how to encrypt data for storage (Secure Cell) or for sending it over network (Secure Message and Secure Session). Java.
