Default implementation of OOSecureURLGenerator which will generate secured Ooyala API URLs using API key and secret.
OOEmbeddedSecureURLGenerator.
Note that embedding your API key and secret into the app is not very secure. To minimize the risk, use read-only API keys if possible. Alternatively, implement your own OOSignatureGenerator and keep the API keys and secrets on server-side.
