These tests execute calls against a local secure (TLS-enabled) Showcase server. During the TLS + * handshake, the client and server negotiate cipher suites and key exchange groups. Showcase + * injects information about the negotiated TLS connection parameters into custom headers: + * + *

    + *
  • {@code x-showcase-tls-group}: The negotiated key exchange named group (e.g. + * X25519MLKEM768). + *
  • {@code x-showcase-tls-version}: The TLS version negotiated (e.g. TLS 1.3). + *
  • {@code x-showcase-tls-cipher}: The negotiated cipher suite (e.g. TLS_AES_128_GCM_SHA256). + *
  • {@code x-showcase-tls-client-supported-groups}: The list of groups offered by the client. + *
+ * + *

To enable PQC, Conscrypt must be available on the classpath. + * + *

    + *
  • For gRPC, the shaded Netty transport dynamically registers and uses Conscrypt natively if + * the Conscrypt library is available on the classpath. + *
  • For HTTP/JSON, the {@link NetHttpTransport} automatically registers Conscrypt as a security + * provider dynamically during transport construction. + *
+ * + * Consequently, these tests do not explicitly register Conscrypt in the global JVM provider list + * during setup. + * + *

Verification cases: + * + *

    + *
  1. {@code testGrpcPqc}: Verifies that gRPC (Netty-shaded) uses Conscrypt and successfully + * negotiates the hybrid post-quantum group {@code X25519MLKEM768}. + *
  2. {@code testHttpJsonPqc}: Verifies that HTTP/JSON transport defaults to Conscrypt and + * negotiates the hybrid post-quantum group {@code X25519MLKEM768}. + *
  3. {@code testHttpJsonPqc_withExplicitSecurityProvider}: Verifies that overriding the + * transport's SSLSocketFactory to explicitly use standard JDK JSSE provider (SunJSSE) falls + * back gracefully to classical key exchange ({@code X25519}) instead of crashing. + *
