Alternatively, use the following command to generate a private RSA key protected by a password:
```sh
openssl genrsa -aes256 -out private.key 2048 -passout pass:PASSWORD
openssl genrsa -aes256 -passout pass:PASSWORD -out private.key 2048
```
**Note:** When using a password-protected private key, the password must be provided through the environment variable `MINIO_CERT_PASSWD` using the following command:
```sh
export MINIO_CERT_PASSWD=<PASSWORD>
```
```
The default OpenSSL format for private encrypted keys is PKCS-8, but MinIO only supports PKCS-1. An RSA key that has been formatted with PKCS-8 can be converted to PKCS-1 using the following command:
```sh
openssl rsa -in private-pkcs8-key.key -aes256 -passout pass:PASSWORD -out private.key
```

#### <a name="generate-a-self-signed-certificate"></a>3.2.3 Generate a self-signed certificate.
Use the following command to generate a self-signed certificate and enter a passphrase when prompted:
```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>"
```
**Note:** Replace `<domain.com>` with the development domain name.
Alternatively, use the command below to generate a self-signed wildcard certificate that is valid for all subdomains under `<domain.com>`. Wildcard certificates are useful for deploying distributed MinIO instances, where each instance runs on a subdomain under a single parent domain.
```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>"
```
