Encrypted

extension MoEngageStorage.UserDefaultStorage.Encrypted


                    
                    
                    process(get:set:dictionary:scope:sdkInstance:)

Intercepts get, set, and dictionary to apply AES encryption/decryption.

The processor is a no-op when:

The scope is not .sdk(.instance).
Encryption is disabled in sdkInstance.storedConfig.storageConfig.encryptionConfig. In that case all encrypted data is cleared from the suite before delegating to the upstream closures, so a device that had encryption enabled previously is cleaned up automatically.

When encryption is enabled, the processor:

Calls encryptionResult(userDefaults:scope:sdkInstance:get:set:dictionary:) on every read/write to determine (and lazily apply) the encryption state.
Decrypts values on get using aesHandler(withKey:).
Encrypts values on set via encryptAndSet(userDefaults:key:value:encryptionKey:sdkInstance:action:).

Throws

Error/noEncryptionKey when a key is needed but unavailable.

Declaration

Swift

public func process(
    get: @escaping @Sendable (isolated MoEngageSDKInstance, UserDefaults, String) throws -> Any?,
    set: @escaping @Sendable (isolated MoEngageSDKInstance, UserDefaults, String, Any?) throws -> Void,
    dictionary: @escaping @Sendable (isolated MoEngageSDKInstance, UserDefaults) throws -> [String: Any],
    scope: MoEngageStorage.UserDefaultStorage<Value>.Scope,
    sdkInstance: isolated MoEngageSDKInstance = #isolation
) throws -> MoEngageStorage.UserDefaultStorage<Value>.ProcessorResult

Parameters

`get`	The upstream `get` closure accumulated by prior processors.
`set`	The upstream `set` closure accumulated by prior processors.
`dictionary`	The upstream `dictionary` closure accumulated by prior processors.
`scope`	The scope of the owning `MoEngageStorage/UserDefaultStorage`.
`sdkInstance`	The isolated SDK instance providing encryption config.

Return Value

.skip when the scope or config does not require encryption; otherwise .transformed with closures that wrap the originals with encrypt/decrypt logic.
