Acrypto works with request/response model, i.e. you ask acrypto core to perform some operation on given buffers and if it can, it will call your callback when it is ready (or some error happend and acrypto was unable to reroute request to other device), otherwise it will return error. With such a model it is possible to extend acrypto to any kind of operations on buffers, not only crypto related, for example it is possible to onload IPsec header transformation, perform DMA between specified areas and much more. -- Evgeniy Polyakov - To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
