help request: SSL private key encryption?

[C2022021]

Description

I found ssl section in config-default.yaml has a key_encrypt_salt attribute, and comment of it said:
# If not set, will save origin ssl key into etcd.
# If set this, must be a string of length 16. And it will encrypt ssl key with AES-128-CBC
# !!! So do not change it after saving your ssl, it can't decrypt the ssl keys have be saved if you change !!

But, After I setting certificate and key through APISIX Dashboard, I still can get origin ssl key from etcd by command etcdctl get --prefix "/apisix/ssl" instead of encrypt string.
I am confused that is the key encryption function has not imlpement for apisix version 2.13.3 on RHEL ? Or anything I had setting wrong in my config file?

Environment

• APISIX version (run apisix version): 2.13.3
• Operating system (run uname -a): RHEL 8.6
• OpenResty / Nginx version (run openresty -V or nginx -V):
• etcd version, if relevant (run curl http://127.0.0.1:9090/v1/server_info): 3.4.13
• APISIX Dashboard version, if relevant: 2.13.0
• Plugin runner version, for issues related to plugin runners:
• LuaRocks version, for installation issues (run luarocks --version):

cc @bzp2010 . I'm not sure if this feature is implemented by Dashboard.

The upload cert apis in apisix-dashboard and apisix are different, the one in apisix will encrypt ssl key, and apisix-dashboard will not. you could upload ssl certs with utils/create-ssl.py, like ./create-ssl.py t.crt t.key test.com, we would unify apisix-dashboard and apisix later.
