All com.sun.crypto.** classes are JDK internal APIs that are not supported and should not be used. This issue documents the supported APIs that you should migrate to use.

Use of com.sun.crypto.provider.SunJCE should be replaced with java.security.Security.getInstance("...") and see Crypto Providers Documentation [1] for details.
