Darchitecture.rst57 Synchronous And Asynchronous Operation
63 When using the synchronous API operation, the caller invokes a cipher
64 operation which is performed synchronously by the kernel crypto API.
65 That means, the caller waits until the cipher operation completes.
67 For synchronous operation, the set of API calls is small and
70 Asynchronous operation is provided by the kernel crypto API which
71 implies that the invocation of a cipher operation will complete almost
72 instantly. That invocation triggers the cipher operation but it does not
73 signal its completion. Before invoking a cipher operation, the caller
