OpenVPN on ARM cortex-A8: hardware acceleration?

kitschen

We plan on using OpenVPN on a TI "Sitara" ARM Cortex A8 processor (AM3352) embedded device (CPU like in BeagleBone Black).
This CPU has hardware acceleration for cryptography, and this link says that hardware acceleration is available for AES, SHA and MD5.

Will OpenVPN profit from hardware acceleration for these hashes/cyphers? Do I need OpenSSL installed for this?

We currently run OpenVPN with Blowfish. Will OpenVPN using Blowfish profit from the crypto hardware acceleration? Must I recompile with special flags for this? Or need some other driver?

Thanks
Phil

maybe this helps...

--engine [engine-name]
Enable OpenSSL hardware-based crypto engine functionality.

If engine-name is specified, use a specific crypto engine. Use the --show-engines
standalone option to list the crypto engines which are supported by OpenSSL.
