# wolfSSL Asynchronous Cryptography support
|
||
|
|
|
||
|
|
Supported with:
|
||
|
|
* Intel QuickAssist
|
||
|
|
* Marvell (Cavium) Nitrox
|
||
|
|
* Crypto Callbacks (`--enable-cryptocb`)
|
||
|
|
* PK Callbacks (`--enable-pkcallbacks`)
|
||
|
|
|
||
|
|
Requires files from https://github.com/wolfSSL/wolfAsyncCrypt
|
||
|
|
See `async-check.sh` for how to setup.
|
||
|

|
Tested with:
|
||
|
|
* `./configure --enable-asynccrypt --enable-rsa --disable-ecc`
|
||
|
|
* `./configure --enable-asynccrypt --disable-rsa --enable-ecc`
|
||
|
|
* `./configure --enable-asynccrypt --enable-cryptocb --enable-rsa --disable-ecc`
|
||
|
|

## Asynchronous Cryptography Design
|
||
|
|
|
||
|
|
When a cryptogaphic call is handed off to hardware 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.
