It was very likely done independently around the same time. The
CroquetPlugin also has a primitive which you may be interested in:
primitiveGatherEntropy, which can fill up a ByteArray with random bytes.
It's available as Random class >> #gatherEntropyInto: in recent Squeak

I've uploaded the code I mentioned before which implement various hash
functions including SHA512. In an image with no Cryptography loaded,
Then you can write:
HashFunction newSHA512 hashMessage: 'test'.
