Disabling some SSL ciphers (optional)

Last updated: 8/28/2025

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

Here is the list of the ciphers supported by Talend JobServer:

TLS_KRB5_WITH_3DES_EDE_CBC_MD5
