Exception while enabling fips in es7.17

While enabling the fips with the below config param we are facing

xpack.security.fips_mode.enabled: true
xpack.security.authc.password_hashing.algorithm: pbkdf2_10000

xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.client_authentication: required
#xpack.security.transport.ssl.keystore.path: certs/elastic-certificates.p12
#xpack.security.transport.ssl.truststore.path: certs/elastic-certificates.p12

closing connection io.netty.handler.codec.DecoderException: javax.net.ssl.SSLHandshakeException: no cipher suites in common

we also tried the below param addition, but facing the same issue

xpack.security.http.ssl.cipher_suites: ["TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256"]

Which JSSE library are you using?
Have you installed a FIPS certified security provider?

Hi @TimV

We are using FIPS installed OS

It's fine to answer on your own thread after 2 or 3 days (not including weekends) if you don't have an answer.


From what you've shown it doesn't look like your Java SDK is configured for FIPS, but I don't know exactly what Ubuntu might be doing under the covers.

My guess is that Ubuntu's JDK packages for FIPS are configured to use non-default settings and have disable certain TLS ciphers.

Elasticsearch's FIPS mode officially only supports running on the Oracle JDK with Bouncy Castle FIPS

FIPS 140-2 mode requires Oracle JDK 11 and the Bouncy Castle BCJSSE FIPS security provider

I suspect your issues are coming from using a different FIPS-enabled JDK.

Hi @TimV

For enabling the fips mode, is it mandatory to go oracle jdk 11 or any other open jdk as per the support matrix

If you want support, then you need to stick to what is listed on the support matrix.
