comment Can you help me understand hash-preserving encryption?
Tylo, thanks for the input. I agree it's unlikely full security can be achieved this way, so I'm looking towards partial security, where forgery would be merely complicated not impossible. It seems to me that "destroying all structure" property can be still hold, but because of some interplay between encryption method and hashing method we could draw an inference mentioned in 1. Well, clearly my intuitiin in crypto is rather weak.

Dear Paulo, thanks for your answer. As you state yourself, this solution, while cleary satisfying 1, has zero security in sense of 2. I was intererested in comparing various approaches to find the most secure in this sense.

The question if there is any encryption / hash pair which will make it work, there is no specific scheme I have in mind at the moment.
