Is this actually Kosher?
Open your Tomcat server
Open your server.xml file in tomcat
Add the connector with TLS protocol as below
<Connector port="8453"
protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150"
maxHttpHeaderSize="16384"
compression="on"
scheme="https"
SSLEnabled="true"
secure="true"
defaultSSLHostConfigName="test.test">
<UpgradeProtocol
className="org.apache.coyote.http2.Http2Protocol" />
<SSLHostConfig
hostName="test.test"
protocols="TLSv1.2"
ciphers="TLS_DHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,
TLS_DHE_DSS_WITH_AES_256_GCM_SHA384,TLS_DHE_RSA_WITH_AES_256_CCM,TLS_ECDHE_ECDSA_WITH_AES_256_CCM,TLS_DHE_RSA_WITH_AES_256_CCM_8,
TLS_ECDHE_ECDSA_WITH_AES_256_CCM_8,TLS_DHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_DHE_DSS_WITH_AES_128_GCM_SHA256,TLS_DHE_RSA_WITH_AES_128_CCM,
TLS_ECDHE_ECDSA_WITH_AES_128_CCM,TLS_DHE_RSA_WITH_AES_128_CCM_8,TLS_ECDHE_ECDSA_WITH_AES_128_CCM_8,
TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256,
TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256">
<Certificate
certificateKeystoreFile="<path to certificate keystore (JKS)>"
certificateKeystorePassword ="${keystore.pass}"
certificateKeyPassword="${keystore.pass}"
certificateKeyAlias="<ALIAS>"
/>
</SSLHostConfig>
</Connector> Now, restart your Tomcat.
If so, do we just add the TLS 1.3 ciphers to the list?
