Difficult:
I understand what a hash is and why it is useful but I had a somewhat difficult time following the example of a hash algorithm. It also seems like we can't really know if we did the hash correctly since we can't reverse the process with the hash and get the message. It seems pretty complicated that we can take in a message of any length and always produce a digest of the same length.
Reflective:
I think it's interesting how we can't reverse the process of a hash. It seems that if we know the algorithm of the hash we would be able to reverse the process since there aren't any private keys or anything like that. I suppose we just lose too much data in the creation of a hash to be able to reverse the process any way at all.
