ECDHE cipher suites not supported on OpenJDK 8 installed on EC2 Linux machine

by

So I’m running a similar setup, with an AWS box running openjdk-1.8.0.51.
what solved it for me is to add bouncycastle as a provider like so:

  • Add the bcprov-<verion>.jar to /usr/lib/jvm/jre/lib/ext

  • Edit /usr/lib/jvm/jre/lib/security/java.security adding the following line to the list of providers: 

    security.provider.6=org.bouncycastle.jce.provider.BouncyCastleProvider

(I added it as the 6th entry but you can add higher in the order if you prefer)

Restarted my application and was able to use EC-based cipher suites such as TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256.
