Strange how papers that discussed encryption discussed hash codes. You better tell them they are wrong.
From a web site on codes and secret messages:
Quote:
There are four main goals of a good cryptographic hash function:
1. It shouldn't require too much computation to calculate the hash of a message (otherwise, websites and other venues would get way too bogged down with dealing with hashes!)
2. If you have a particular hash, you shouldn't be able to invent a message that has that hash
3. If you change even a tiny bit of a message, the new message should have a different hash.

and then says what a good crypotgraphic has code must have:
Quote:
|
And your password is never stored, which means no one can access it.

Without the password in that example (a prime number), then a hash cannot be restored.
Hash codes are not limited to encryption. These are also found in data compression. And in the case of that quantum computer, to extract information from noise. Hash codes also exist for data structures. Another hashing function is called fractals.
You really need to learn stuff before posting your feelings. Since your feeling only want to demean. And not contribute honest answers to the topic.
