If you want to use multiple update keys you can create a keyfolder and tell acme.sh to use it.
Acme.sh then tries to use the key file `${NSUPDATE_KEYDIR}/example.com.key`. If there is none it falls back to the default `NSUPDATE_KEY`.
```
mkdir ~/.acme.sh/keys
export NSUPDATE_KEYDIR="~/.acme.sh/keys"
```
Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_nsupdate -d example.com -d www.example.com
