OpenBSD does their crypto in userland
Where do you get that from? "Classical" WPA2 with preshared keys is entirely handled inside the kernel, with support for WPA Enterprise provided by wpa-supplicant.
Other areas where crypto is required are also in-kernel, such as IPSec packet encryption, with key management done in userspace, the random number generator and the softraid crypto target.
Of course these interact with userspace, for example to configure keys or other algorithm parameters, but the crypto itself runs inside the kernel.
