When submitting an iOS app, do I need to declare that Easy Save uses encryption?

Yes, unless you replace the MoodkieSecurity.dll file included with Easy Save with the blank one found online.
Web Functionality uses MD5 hashing and Encryption uses 128-bit AES (Symmetric). If you use either of these features, you must declare that you use encryption when asked.
If you are unsure of anything regarding this matter, contact Apple, as we cannot assist with this process.
