## Steps to create and install CA signed certificate

To create and install a CA signed server certificate, follow these steps:

A. Create your own SSL certificate authority

B. Generate CSR for server certificate

C. Create CA signed server certificate using CSR request

D. Install CA signed server certificate

**Create your own SSL certificate authority**

1. Create private key for certificate authority(CA).

`openssl genrsa -des3 -out rootCA.key 2048`

Note: You will be prompted to give a password for private key. This password
will be used whenever the private key is used.

2. Create a root CA certificate using the private key created in step 1.

`openssl req -x509 -new -nodes -key rootCA.key -sha256 -days 1024 -out rootCA.pem`

This will start an interactive script to enter information that will be
incorporated into your certificate request.

```
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:Oregon
Locality Name (eg, city) []:Portland
Organization Name (eg, company) [Default Company Ltd]:XYZ
Organizational Unit Name (eg, section) []:IT
Common Name (eg, YOUR name) []:XYZ CERTIFICATE AUTHORITY
Email Address []:none@none.com
```

**Generate CSR for server certificate**

1. Create CSR request file (csr_file.json) with all of the following fields.

```
{
    "City": <City Name>,
    "CertificateCollection": {
        "@odata.id": "/redfish/v1/Managers/${MANAGER_ID}/NetworkProtocol/HTTPS/Certificates/"
    },
    "CommonName": "<BMC_IP>",
    "Country": <Country Name>,
    "Organization": <Organization Name>,
    "OrganizationalUnit": <Organization Unit Name>,
    "State": <State Name>,
    "KeyPairAlgorithm": <RSA/EC>
}
```

Example:

```
{
    "City": "Austin",
    "CertificateCollection": {
        "@odata.id": "/redfish/v1/Managers/${MANAGER_ID}/NetworkProtocol/HTTPS/Certificates/"
    },
    "CommonName": "xx.xx.xx.xx",
    "Country": "US",
    "Organization": "ABC Limited",
    "OrganizationalUnit": "IT",
    "State": "AU",
    "KeyPairAlgorithm": "RSA"
}
```

2. Generate CSR request using the following Redfish command.

```
$ curl -c cjar -b cjar -k -H "X-Auth-Token: $bmc_token" -X POST https://${BMC_IP}/redfish/v1/CertificateService/Actions/CertificateService.GenerateCSR/ -d @csr_file.json
{

3. Convert response into .csr file (device.csr)

```
$ cat device.csr

**Create CA signed server certificate using CSR request**

1. Use BMC generated CSR request (device.csr) to generate CA signed certificate
   (device.crt).

```
openssl x509 -req -in device.csr -CA rootCA.pem -CAkey rootCA.key -CAcreateserial -out device.crt -days 500 -sha256
```

Note: You will be prompted to give a password for private key.

2. Create JSON file (certificate.json) with the device.crt file created in
   step 1.

```
$ cat certificate.json
{
    "CertificateString": "-----BEGIN CERTIFICATE-----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\nGvsIpb0=\n-----END CERTIFICATE-----",

**Install CA signed server certificate**

Replace server certificate using JSON file (above) with CA signed certificate
details (certificate.json).
