采用 OpenJDK 11 中的 JCE

Question

可以找到 Java 加密扩展 (JCE) here ，但那个页面说

Current versions of the JDK do not require these policy files. They are provided here for use with older version of the JDK.

JDK 9 and later ship with, and use by default, the unlimited policy files.

这是否适用于 AdoptOpenJDK 11也是吗？或者这仅限于 Oracle 的 JDK？我怎么知道它们可用？

根据 this guide :

I’ve been asked whether Java’s Cryptography/Security extension (JCE) is supported in OpenJDK. The answer is yes it is. As a note, in OpenJDK as of 8b161, unlimited cryptography policy is enabled by default (previously you had to download the unlimited strength files manually from Oracle).
