Secure Key Exchange Service
Build a secure key exchange service that establishes shared secrets between two parties using standardized cryptographic parameters.
Requirements
Your service should provide functionality to:
- Initialize key exchange instances using standardized cryptographic parameters rather than generating custom parameters
- Generate key pairs for each party in the exchange
- Compute shared secrets by exchanging public keys between parties
- Support multiple security levels by allowing selection of different standardized parameter sets
- Export public keys in hexadecimal format for transmission between parties
Test Cases
- It successfully establishes matching shared secrets between two parties using the 'modp5' parameter set @test
- It successfully establishes matching shared secrets using the 'modp14' parameter set @test
- It returns hexadecimal-encoded public keys @test
- It produces identical shared secrets when computed by both parties @test
