Supported TLS and SSL protocols and ciphers#

UrbanCode™ Deploy supports multiple SSL protocols and ciphers for communication between servers.

UrbanCode Deploy supports TLSv1, TLSv1.1, and TLSv1.2 SSL protocols. UrbanCode Deploy supports only the SSLv3 protocol if older agents require its use. See Upgrading agents.

Note: Limiting and disabling SSL and TLS protocols and ciphers is done at the JVM level rather than the application level.

UrbanCode Deploy uses SSL in communication between the web UI and the server and between servers that use ActiveMQ. The SSL certificates that control both types of communication use the Java™ KeyStore (JKS) format. The certificates are generated by an RSA key with a 2048-bit length and are signed by a SHA256withRSA algorithm.

The list of SSL ciphers you can use depends on which ciphers the Java crypto provider of the JRE supports on which you installed your UrbanCode Deploy server, relay and agent.
