Unraid does not come with the `xxd` command installed. There used to be a package called NerdTools that I used to use but it looks like it was removed. I do not recall if you can use `docker run` in Unraid, but these commands can be used. A quick google indicates [windows users can use the docker cli](https://learn.microsoft.com/en-us/virtualization/windowscontainers/quick-start/set-up-environment?tabs=dockerce).

```bash
|
|
# on host
|
|
docker run --rm -it alpine:latest sh
|
|
|
|
# in container
|
|
apk add xxd openssl
|
|
|
|
# everything after this is one command
|
|
echo PDS_PLC_ROTATION_KEY_K256_PRIVATE_KEY_HEX: $(openssl ecparam --name secp256k1 --genkey --noout --outform DER | tail -c +8 | head -c 32 | xxd --plain --cols 32)
|

```
