SSL ciphers are encryption algorithms that are used to establish a secure
communication. Some cipher suites offer a lower level of security than others, and you
may want to disable these ciphers.
Procedure
-
Go to the directory <root>/conf/ and
open the TalendJobServer.properties file.
-
Add to the following parameter the list of ciphers that you want to
disable:
org.talend.remote.jobserver.server.TalendJobServer.DISABLED_CIPHER_SUITES
