Rishabh Srivastav developed HTTP/2 support for the confluentinc/rest-utils repository, focusing on secure integration with FIPS-compliant environments. He introduced the BouncyCastleServerALPNProcessor, extending Jetty’s JDK9ServerALPNProcessor to enable ALPN negotiation when using the BouncyCastle FIPS JSSE provider. By implementing runtime detection of the BouncyCastle SSLEngine, Rishabh ensured that HTTP/2 handshakes functioned correctly with FIPS modules, addressing compliance and security requirements. He also backported these enhancements to the 7.5.x branch to maintain consistency across releases. His work demonstrated depth in backend development, Java, and cryptography, delivering a robust solution for secure HTTP/2 communication.
