Using Themis in Objective-C #

ObjCThemis wrapper provides access to features of Themis cryptographic library for Apple platforms:

• 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 Swift and React Native.

Important: If your application uses Themis and you want to submit it to the Apple App Store, there are certain requirements towards declaring use of any cryptography.
