It looks like OpenJDK will still require you to set a system property to enable "unlimited strength cryptography". Important Oracle Java License Information The Oracle Java License changed for releases starting April 16, 2019. Oracle Java 9 will include the "unlimited strength cryptography" libraries enabled by default, so that's nice. That is all that is required in order to enable Elliptic-Curve algorithms. ![]() This means that, if you can grab a copy of Oracle's JRE/JDK for the target platform and architecture, you can take the libsunec.so library from it and install it legally into the OpenJDK installation.įor me, that meant grabbing the file $JAVA_HOME/jre/lib/amd64/libsunec.so from an Oracle Java 8 JRE and dropping it into e.g. You can confirm this by going to Oracle's download page, clicking on Third Party Licenses, and checking the README for your version of Java. It seems that Oracle's Elliptic curve native library ( libsunec.so) is licensed under the GPL. It looks like OpenJDK on Amazon Linux will just have to wait. ![]() Ideally, the JDK would provide native implementations which would yield higher performance. The accepted answer of "install Bouncy Castle" works because BC provides a pure-Java implementation of all the desired algorithms. If the libraries aren't there, you can't use the features. The Unlimited Policy Files are a red herring, as are any attempts to un-disable various algorithms, etc. The root cause is that OpenJDK on CentOS/RHEL/Amazon Linux with OpenJDK on them simply do not ship with the required native libraries to support EC. Oracle's JCE cryptographic provider is installed under jre/lib/security/, but it didn't help. Download java-1.8. Im pretty new to Linux and I need to install openjdk 1.8.020-b26 (that specific version) on a machine in AWS. I read Oracle Java 8 should support these protocols, but maybe that's not supported by OpenJDK? Or should I enable it somehow?

OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode) So I logged into our production server (Ubuntu 16.04) and there we've got something similar: $ java -version Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)Īs far as I know Java is WAY ahead of version 1.8. Java(TM) SE Runtime Environment (build 1.8.0_191-b12) So I checked which version I have on my Ubuntu 18.04 laptop so he can get the same one, and to my surprise it says: $ java -version When he has Java version 7, 8 or 9 installed he gets a message saying we need legacy java you can download it here.Īnd if he uses Java version 6, it says it needs version 7 or more. I've got FDT working on my Ubuntu 18.04 laptop just fine, but the dev is having trouble getting it to work on his Mac. On of our (remote) developers needs to install FDT (an Eclipse based IDE) to compile some legacy ActionScript code. ![]()
