Merge #19934: tests: Add fuzzing harness for Keccak and SHA3_256
fc7f84a9ca98ee0d9c2d1f092be6b5dba3f2a582 tests: Add fuzzing harness for Keccak and SHA3_256 (practicalswift)
Pull request description:
Add fuzzing harness for Keccak and SHA3_256.
See [`doc/fuzzing.md`](https://github.com/bitcoin/bitcoin/blob/master/doc/fuzzing.md) for information on how to fuzz Bitcoin Core. Don't forget to contribute any coverage increasing inputs you find to the [Bitcoin Core fuzzing corpus repo](https://github.com/bitcoin-core/qa-assets).
Happy fuzzing :)
