A high-level cryptographic library providing secure data storage, messaging, and session encryption with unified APIs across 14+ platforms.
Themis is an open-source high-level cryptographic services library that provides secure data storage, messaging, and session encryption for applications. It solves common data protection use cases like encrypting stored secrets, securing sensitive database fields, and enabling end-to-end encrypted communication. The library offers ready-made cryptosystems that simplify complex cryptographic operations, making it accessible to developers without deep cryptography expertise.
Developers building multi-platform applications (mobile, web, desktop, server) that require robust data encryption, secure messaging, or compliance with regulations like GDPR, HIPAA, or CCPA. It's ideal for teams needing a consistent cryptographic API across iOS, Android, React Native, Java, Python, Go, and other supported platforms.
Developers choose Themis because it provides a unified, high-level API across 14+ platforms, eliminating the need to implement cryptography from scratch. It offers strong security built by cryptographers, simplifies complex operations with ready-made cryptosystems, and helps achieve compliance with data privacy regulations through state-of-the-art encryption.
Easy to use cryptographic framework for data protection: secure messaging with forward secrecy and secure data storage. Has unified APIs across 14 platforms.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Offers identical cryptographic APIs across 14+ platforms like iOS, Android, and WebAssembly, simplifying development for cross-platform apps as highlighted in the README.
Provides high-level cryptosystems like Secure Cell and Secure Message that abstract away complex details, reducing implementation time and errors for common use cases.
Built and regularly audited by cryptographers with automated testing, ensuring reliability for compliance with regulations like GDPR and HIPAA, as noted in the security docs.
The high-level APIs restrict access to underlying cryptographic parameters, making it unsuitable for advanced customizations or novel algorithms beyond the 90% of use cases it targets.
Windows support is labeled as experimental via MSYS2 in the README, which can lead to integration difficulties and instability in production environments compared to more mature platforms.
