Disabling some SSL ciphers (optional)

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

  1. Go to the directory <root>/conf/ and open the TalendJobServer.properties file.
  2. 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
TLS_KRB5_WITH_RC4_128_SHA
SSL_DH_anon_WITH_DES_CBC_SHA
