Using Themis in Java #

JavaThemis wrapper provides access to features of Themis cryptographic library for Java and Android applications:

• Key generation: securely generate strong key pairs and symmetric keys.
• Data storage at rest: encrypt sensitive data for storage with symmetric cryptography.
• Authenticated messaging: exchange messages which are readable only by the recipent using asymmetric cryptography, or sign messages with your private key to prove identity.
• Protect data in motion: establish a session between a client and a server for secure data exchange with perfect forward secrecy guarantees.
• Secret comparison: verify that the other party has the same shared secret as you have — without disclosing anything about the secret to anyone — using zero-knowledge proofs.

Themis can also be used with Kotlin and React Native.

Supported Java versions #
