From a theoretical perspective, applying encryption/decryption is more like applying an isomorphism, that is, turning one mathematical structure into an equivalent mathematical structure (with no information loss). I cannot see how this is a "creating" action, let alone a "creative" one.

Now, such isomorphisms turning one information into another could in theory be found for any two pieces of information, but here we are talking about a very limited family of isomorphisms between spaces of all finite binary sequences, so there is little to no creativity involved in selecting and using such an encryption function.
