Using Themis in PHP #

PHPThemis extension provides access to features of Themis cryptographic library in PHP:

• 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.

PHPThemis does not support secure comparison — verification of shared secret ownership using zero-knowledge proofs. This feature is currently in development for PHPThemis.
