openssl: missing engine libcryptodev.so

[Jon Blackfuel]

Package: openssl

I want to test the openssl with /dev/crypto interface, however this engine is missing.

Platform:

ASUS RT-AC86U router, armv8-a
Linux 3.x kernel, aarch64

Results

# /opt/bin/openssl speed -evp aes-256-cbc -engine cryptodev -elapsed
invalid engine "cryptodev"

My guess - you need appropriate kernel headers to build libcryptodev.so
We use vanilla linux kernel to make Entware universal.
The compile openssl with CONFIG_OPENSSL_HARDWARE_SUPPORT=y as configure by openwrt buildroot.
If you know how to build universal openssl with cryptoengine support - please report.
