FAQ for Unity SDK

Why are there two subscribe methods?

The Unity SDK supports a modern, entity-based flow and retains a legacy Subscribe<string>() for backward compatibility.

Use the modern flow documented in Subscribe. It creates a Subscription or a SubscriptionSet, uses an event listener, and can resume from a timetoken using a SubscriptionCursor. The legacy builder pubnub.Subscribe<string>() is documented in Subscribe (old) and remains for existing applications.

Why does encryption use AES-128 when CryptoModule is configured?

If you pass the cipherKey argument to Encrypt, Decrypt, EncryptFile, or DecryptFile, that argument overrides the configured CryptoModule for that single operation and uses legacy Advanced Encryption Standard (AES) with 128-bit keys. Omit the cipherKey argument to use the CryptoModule configuration (AES‑256‑CBC). For partial encryption, create a separate CryptoModule instance and call it directly where needed.

For details, refer to CryptoModule configuration.
