 ## Asynchronous Cryptography Design
 
-When a cryptogaphic call is handed off to harware it return `WC_PENDING_E` up to caller. Then it can keep calling until the operation completes. For some platforms it is required to call `wolfSSL_AsyncPoll`. At the TLS layer a "devId" (Device ID) must be set using `wolfSSL_CTX_SetDevId` to indicate desire to offload cryptography.
