-While Secretive uses the Secure Enclave for key storage, it still relies on Keychain APIs to access them. Keychain restricts reads of keys to the app (and specifically, the bundle ID) that created them. If you build Secretive from source, make sure you are consistent in which bundle ID you use so that the Keychain is able to locate your keys.
