Hi Neale, I’m really new to VPP and can you tell me where’s the plugins you mentioned? Thanks a lot.

Since there’s no example for the command, I’m not sure if I’m setting the right value for ‘cipher’ here. I tried with different values, but it just returns error msg like this: vpp# set crypto handler aes-128-cbc engine failed to set engine engine for aes-128-cbc! vpp# set crypto handler openssl engine failed to set engine engine for openssl! And according to the wiki page here( https://wiki.fd.io/view/VPP/IPSec) that there’re three choices for the engines. But I cannot get any of them work ☹. Any other clues for registering the engines? Thanks a lot.

I think you’ve pointed out the root cause. The cmds provides the response like this: vpp# show crypto engine No crypto engines registered vpp# show ipsec backend IPsec AH backends available: Name Index Active crypto engine backend 0 yes IPsec ESP backends available: Name Index Active crypto engine backend 0 no dpdk backend 1 yes Looks like that no crypto engine is registered. I’m checking the related docs, but are the engines registered by default or we need to manually register them? Thanks.
