Instead of `strings` for the search[1], I recommend using `rz-bin`[2] and `rz-find`[3] tools, which offer more flexibility, searching strings outside of the data sections, searching for Unicode and less common encodings, and built-in cryptographic keys search. There are also `/` (search) commands in the Rizin itself. As for the entropy, there is a configurable and interactive histogram, see `p=` and `p==` commands, e.g. `p==e`.
