To use the JCA, an application simply requests a particular type of object (such as a MessageDigest) and a particular algorithm or service (such as the "SHA-256" algorithm), and gets an implementation from one of the installed providers. Alternatively, the program can request the objects ...

Alternatively, the program can request the objects from a specific provider. Each provider has a name used to refer to it. For example, the following statement requests a SHA-256 message digest from the provider named ProviderC: Copy md = MessageDigest.getInstance("SHA-256", "ProviderC"); ...
