**Generate the self-signed certificate**:
Generate self-signed certificate using the below command (remember to replace `<domain.com>` with your actual domain name)
```sh
openssl req -new -x509 -days 3650 -key private.key -out public.crt -subj "/C=US/ST=state/L=location/O=organization/CN=domain"
openssl req -new -x509 -days 3650 -key private.key -out public.crt -subj "/C=US/ST=state/L=location/O=organization/CN=<domain.com>"
```
Generate self-signed wildcard certificate using the below command. This certificate will be valid for all the sub-domains under `domain.com`. Wildcard certificates come in handy while deploying distributed Minio instances where there may be multiple sub-domains under a single domain, with each one running a separate Minio instance.
```sh
openssl req -new -x509 -days 3650 -key private.key -out public.crt -subj "/C=US/ST=state/L=location/O=organization/CN=<*.domain.com>"
```

- Acquire TLS certificates, either from a CA or [create self-signed certificates](https://docs.minio.io/docs/how-to-secure-access-to-minio-server-with-tls).
For a [distributed Minio setup](https://docs.minio.io/docs/distributed-minio-quickstart-guide), where there are multiple pods with different domain names expected to run, you will either need wildcard certificates valid for all the domains or have specific certificates for each domain. If you are going to use specific certificates, make sure to create Kubernetes secrets accordingly.
For testing purposes, here is [how to create self-signed certificates](https://github.com/minio/minio/tree/master/docs/tls#3-generate-self-signed-certificates).
## 2. Create Kubernetes secret
[Kubernetes secrets](https://kubernetes.io/docs/concepts/configuration/secret) are intended to hold sensitive information.
