Themis is an open-source high-level cryptographic services library for mobile and server platforms, which provides secure data exchange and storage.
- What is Themis: a bird's eye view of Themis.
- Going deeper: an in-depth look at the architecture and construction of Themis.
- Soter: core crypto library: the underlying cryptographic primitive layer in Themis.
- On cryptographic donors: making sure our solutions are based only on high-quality verified code through utilising the existing open-source cipher implementations.
-
Cryptosystems: what they are and how they create Themis Objects (a general explanation).
- Secure Message: asymmetric encryption for data transfer.
- Secure Session: asymmetric encryption based on ephemeral keys.
- Secure Cell: container for symmetric/storage encryption.
- Secure Comparator: ZKP implementation (comparing shared secret, without revealing it to potentially dishonest party).
- Building and installing: detailed instructions for when the default installation scenario fails (this is rare, but not impossible).
