ios - ITSAppUsesNonExemptEncryption export compliance while internal testing?

Question

I got this message while selecting build for internal testing.it says about setting ITSAppUsesNonExemptEncryption in info.plist what does it mean? is it necessary?

Answer 1

Basically <key>ITSAppUsesNonExemptEncryption</key><false/> stands for a Boolean value equal to NO.

Update by @JosepH: This value means that the app uses no encryption, or only exempt encryption. If your app uses encryption and is not exempt, you must set this value to YES/true.

It seems debatable sometimes when an app is considered to use encryption.
