示例1: testCleanupSecret
import javax.crypto.SecretKey; //导入方法依赖的package包/类
static void testCleanupSecret(String algorithm) throws Exception {
KeyGenerator desGen = KeyGenerator.getInstance(algorithm, SunJCEProvider);
SecretKey key = desGen.generateKey();
// Break into the implementation to observe the key byte array.
Class<?> keyClass = key.getClass();
Field keyField = keyClass.getDeclaredField("key");
keyField.setAccessible(true);
byte[] array = (byte[])keyField.get(key);
byte[] zeros = new byte[array.length];
do {
// Wait for array to be cleared; if not cleared test will timeout
System.out.printf("%s array: %s%n", algorithm, Arrays.toString(array));
key = null;
System.gc(); // attempt to reclaim the key
} while (Arrays.compare(zeros, array) != 0);
System.out.printf("%s array: %s%n", algorithm, Arrays.toString(array));
Reference.reachabilityFence(key); // Keep key alive
Reference.reachabilityFence(array); // Keep array alive
}
