The virtio crypto device is a virtual crypto device, and is a kind of virtual hardware accelerator for virtual machines. The encryption and decryption requests are placed in the data queue, and handled by the real crypto accelerators finally. The second queue is the control queue, which is used to create or destroy sessions for symmetric algorithms, and control some advanced features in the future. The virtio crypto device can provide seven crypto services: CIPHER, MAC, HASH, AEAD, KDF, ASYM, PRIMITIVE.

Code
- Virtio-crypto specification: Gonglei's virtio.git
- Virtio-crypto linux driver: Gonglei's virtio-crypto-linux-driver.git
- QEMU: Gonglei's qemu.git
- Cryptodev-linux: Cryptodev-linux's website Cryptodev-linux is implemented as a standalone module that requires no dependencies other than a stock linux kernel.
Quickstart
Host:
- Step 1: Use the cryptodev-linux as the client, the cryptodev.ko should be insert on the host.
Cryptodev:
$ git clone https://github.com/cryptodev-linux/cryptodev-linux.git $ cd cryptodev-linux $ make; make install
- Step 2: Build qemu with cryptodev-linux support
QEMU:
$ git clone -b virtio-crypto https://github.com/gongleiarei/qemu $ cd qemu $ ./configure --target-list=x86_64-softmmu $ make
Guest:
- Step 1: Build and install virtio-crypto linux driver.
$ git clone https://github.com/gongleiarei/virtio-crypto-linux-driver.git $ cd virtio-crypto-linux-driver $ make;make install
- Step 2: use cryptodev-linux test the crypto functions
Testing
Use the cryptodev-linux module to test the crypto functions in the guest.
$ cd qemu
$ make -j4
$ make tests/vhost-vsock-test
$ sudo QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 QTEST_QEMU_IMG=qemu-img MALLOC_PERTURB_=${MALLOC_PERTURB_:-$((RANDOM % 255 + 1))} gtester -k --verbose -m=quick tests/vhost-vsock-test -o /dev/stderr
Create and edit test cases in tests/vhost-vsock-test-data/*.json.
