-The above example uses the `DigestSink` class that comes with the
-_crypto_ package. Its `value` property retrieves the last `Digest`
-that was added to it, which is fine for this purpose since only one
-`Digest` is added to it when the data sink's `close` method was
-invoked.
+The above example uses the `AccumulatorSink` class that comes with the
+_convert_ package. It is capable of accumulating multiple events, but
+in this usage only a single `Digest` is added to it when the data sink's
+`close` method is invoked.
