OK, I will remove the ` = (digest length x 2)` words from `keccak()`. As for the synopsis, this bug was about the bug in SHAKE256, and I don’t know how to add SHAKE128 there. One solution is to remove `SHAKE128.java` at all from this code change, and I can add it into my other PR at [RFE 4936767: Parameters for MessageDigest](https://github.com/openjdk/jdk/pull/16660). How do you think of this?
