My application is a Vert.x based application and recently switched to use OpenSSLEngineOptions which uses netty-tcnative for listening on a secure protocol. Earlier I was using code like below in order to disable older TLS versions, but post switching to OpenSSLEngineOptions, the same does not seem to be working.
Security.setProperty("jdk.tls.disabledAlgorithms", "RC4,TLSv1");
Note that I am not allowed to modify the java.security file as the box may be used to run other unrelated Java applications.
Seems like I have an option to use io.vertx.core.http.HttpServerOptions#addEnabledSecureTransportProtocol method to achieve the same (actually reverse, but not yet tested), but this involves a code change and thus a release which means a process to follow. Please share if any inputs around this if tcnative supports any other system properties that can limit the protocols exposed.
