Hi, This applies to JDK 11. https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/security/interfaces/XECKey.html what is the value of "AlgorithmParameterSpec"?
In JDK 15 the new EdECKey has gotten a more logical solution: https://download.java.net/java/early_access/jdk15/docs/api/java.base/java/security/interfaces/EdECKey.html thanx, Anders
