+## 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) [Internet Widgits Pty Ltd]:Overlords
+Organizational Unit Name (eg, section) []:IT
+Common Name (eg, YOUR name) []:Data Center Overlords
+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/bmc/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/bmc/NetworkProtocol/HTTPS/Certificates/"
+    },
+    "CommonName": "9.3.111.222",
+    "Country": "US",
+    "Organization": "IBM",
+    "OrganizationalUnit": "ISL",
+    "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

+  "CertificateCollection": {
+    "@odata.id": "/redfish/v1/Managers/bmc/NetworkProtocol/HTTPS/Certificates/"
+  }
+}
+```
+
+4. Convert response into .csr file (device.csr)
+
+```
+$ cat device.csr
+-----BEGIN CERTIFICATE REQUEST-----

+-----END CERTIFICATE REQUEST-----
+```
+
+**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
+```
+
+
+2. Create JSON file (certificate.json) with the device.crt file created in step 1.
+
+```
+$ cat certificate.json
+{
+    "CertificateString": "-----BEGIN CERTIFICATE-----\nMIIC+TCCAeECCQCk+dNJDXfI1jANBgkqhkiG9w0BAQsFADCBmDELMAkGA1UEBhMC\nSU4xDjAMBgNVBAgMBURFTEhJMQ4wDAYDVQQHD  AVERUxISTEeMBwGA1UECgwVQ0VS\nVElGSUNBVEUgQVVUSE9SSVRZMQswCQYDVQQLDAJJVDEeMBwGA1UEAwwVRGF0YSBD\nZW50ZXIgT3ZlcmxvcmRzMRwwGg  YJKoZIhvcNAQkBFg1ub25lQG5vbmUuY29tMB4X\nDTE5MDYyNzExMTczNloXDTIwMTEwODExMTczNlowgasxJTAjBgNVHREMHHdzYm1j\nMDE1LmF1cy5zdGd  sYWJzLmlibS5jb20xDzANBgNVBAcMBkF1c3RpbjESMBAGA1UE\nAwwJOS4zLjIxLjU1MQ8wDQYDVQQpDAZteW5hbWUxCzAJBgNVBAYTAlVTMQ0wCwYE\nKw4D  AgwDUlNBMRUwEwYDVR0PDAxLZXlBZ3JlZW1lbnQxDDAKBgNVBAoMA0lCTTEL\nMAkGA1UECAwCQVUwXDANBgkqhkiG9w0BAQEFAANLADBIAkEAwY9eVEdOobp  T646S\nsn7QmcxLeoWnCIulyP3hKR2f4E8Cy3FdO/j3HlrlKxJijB8eBDmdB0zR8CnVUipU\ncknj4QIDAQABMA0GCSqGSIb3DQEBCwUAA4IBAQAcYmkbcznF  fOm9bDuIeXHzNSus\nEwOhAberTXWvPMtjbDTmbVH5dRPU+DmgS+LEl2jhYC414R89EUApjrXmk1PzlBrN\nXEnBf9+OHOHOH7H4AIni3diw9PRzEdW5ENHUi  OIVoq7LxWP+RknSHGl8AfOghX/3\n6eRgtpIp+fTYwJkGdZaKb9cI5XXk0Eh1cZZ3W43PNsKbuv1BGLGjJVRRaswF9nb1\ng2M4iZLtVXltdkyHW/Z6TUWvG+  9+TYuKingixv0toaWyRGexjC1CeRORGhyYW8Dz\niGipRCWmVo97MC5sWtQjVAshB1TY6rUqipxzW9SqyjplBD+AHySY/IqGM+wU\n-----END CERTIFICATE-----\n",
