2) Encrypted Zips do not internally store the hash value of the file inside them (as per Zip standard).
As you will have read in the Help, Rename/Move detection requires that file contents be compared (hashed) to be sure the content is the same in both files. An encrypted Zip doesn't contain a hash value, so it's not possible/practical.
