 Previous versions of Node.js exposed handles to internal native objects through
 the `_handle` property of the `Cipher`, `Decipher`, `DiffieHellman`,
 `DiffieHellmanGroup`, `ECDH`, `Hash`, `Hmac`, `Sign`, and `Verify` classes.
-Using the `_handle` property to access the native object is deprecated because
-improper use of the native object can lead to crashing the application.
+The `_handle` property has been removed because improper use of the native
+object can lead to crashing the application.
