OpenEdDSA

OpenEdDSA: A JCE provider that supports KeyPairGenerator, KeyFactory and Signature for the EdDSA crypto algorithms on Java SE 8.

The OpenEdDSA project is created to add support for EdDSA crypto algorithms to existing Java 8 applications without requiring code changes.

The public API for OpenEdDSA is located in the org.openeddsa.java.security.spec and org.openeddsa.java.security.interfaces packages and is similar to the java.security.spec and java.security.interfaces package APIs introduced by JEP-339.

Installation

Installation of OpenEdDSA provider is done in two steps:

1. Add the OpenEdDSA provider jar to the $JAVA_HOME/jre/lib/ext directory
2. Create an OpenEdDSA provider entry in the $JAVA_HOME/jre/lib/security/java.security file

The entry to java.security will look something like the following:

security.provider.N=org.openeddsa.security.OpenEdDSA

Replace N with last entry in the list of providers

Code origins and evolution

The project code is comprised primarily of a backport of the JEP-339 to Java 8. While small modification were needed in order to make the code work on Java 8 JREs, the structure of the original code has been kept mostly intact, with associated packages placed under the org.openeddsa.* namespace to avoid collisions.
