Usage Pattern | 使用模式

use seal_crypto_wrapper::algorithms::asymmetric::kem::KemAlgorithm;

// Post-quantum algorithms (recommended)
let kyber512 = KemAlgorithm::build().kyber512();
let kyber768 = KemAlgorithm::build().kyber768();

// Traditional algorithms (for compatibility)
let rsa = KemAlgorithm::build().rsa2048().sha256();
