Elytron server-ssl-context allowed protocols -------------------------------------------- Key: WFLY-13916 URL: https://issues.redhat.com/browse/WFLY-13916 Project: WildFly Issue Type: Feature Request Reporter: Sonia Zaldana Assignee: Sonia Zaldana Priority: Major SSLv2Hello is used in older JDK versions for the initial handshake message where the SSL version that will be used for the rest of the handshake is negotiated. It is not possible to add SSLv2Hello to the list of protocols in server-ssl-context due to not being a valid value: {code:java} [standalone@localhost:9990 /] /subsystem=elytron/server-ssl-context=my-ssl-context:list-add(name=protocols, value=SSLv2Hello, index=0) { "outcome" => "failed", "failure-description" => "WFLYCTL0129: Invalid value SSLv2Hello for protocols; legal values are [\"SSLv2\", \"SSLv3\", \"TLSv1\", \"TLSv1.1\", \"TLSv1.2\", \"TLSv1.3\"]", "rolled-back" => true }{code}   It is possible to add SSLv2Hello to the https connector in Undertow with legacy security as per.
