 Generate a self-signed certificate for encrypting your secrets:
 
 ```bash
-user@linux:~$ openssl req -newkey rsa:2048 -nodes -keyout TestCert.prv -x509 -days 365 -out TestCert.pem
-user@linux:~$ cat TestCert.prv >> TestCert.pem
+openssl req -newkey rsa:2048 -nodes -keyout TestCert.prv -x509 -days 365 -out TestCert.pem

 ```
 
 Use the instructions in [Deploy Key Vault certificates to Service Fabric cluster virtual machine scale sets](#deploy-key-vault-certificates-to-service-fabric-cluster-virtual-machine-scale-sets) to your Service Fabric Cluster's Virtual Machine Scale Sets.
 
 Encrypt your secret using the following commands, and then update your Service Fabric Application Manifest with the encrypted value:
 
 ```bash
-user@linux:$ echo "Hello World!" > plaintext.txt
-user@linux:$ iconv -f ASCII -t UTF-16LE plaintext.txt -o plaintext_UTF-16.txt
-user@linux:$ openssl smime -encrypt -in plaintext_UTF-16.txt -binary -outform der TestCert.pem | base64 > encrypted.txt

 ```
 
 After encrypting your protected values, [specify encrypted secrets in Service Fabric Application](./service-fabric-application-secret-management.md#specify-encrypted-secrets-in-an-application), and [decrypt encrypted secrets from service code](./service-fabric-application-secret-management.md#decrypt-encrypted-secrets-from-service-code).

 In your Service Fabric application code, [obtain an access token](../active-directory/managed-identities-azure-resources/how-to-use-vm-token.md#get-a-token-using-http) for Azure Resource Manager by making a REST all similar to the following:
 
 ```bash
-access_token=$(curl 'http://169.254.169.254/metadata/identity/oauth2/token?api-version=2018-02-01&resource=https%3A%2F%2Fmanagement.azure.com%2F' -H Metadata:true | python -c "import sys, json; print json.load(sys.stdin)['access_token']")
+ACCESS_TOKEN=$(curl 'http://169.254.169.254/metadata/identity/oauth2/token?api-version=2018-02-01&resource=https%3A%2F%2Fmanagement.azure.com%2F' -H Metadata:true | python -c "import sys, json; print json.load(sys.stdin)['access_token']")
 
 ```
 
 Your Service Fabric app can then use the access token to authenticate to Azure Resources that support Active Directory.
 The following example shows how to do this for a Azure Cosmos DB resource:
 
 ```bash
-cosmos_db_password=$(curl 'https://management.azure.com/subscriptions/<YOUR SUBSCRIPTION>/resourceGroups/<YOUR RG>/providers/Microsoft.DocumentDB/databaseAccounts/<YOUR ACCOUNT>/listKeys?api-version=2016-03-31' -X POST -d "" -H "Authorization: Bearer $access_token" | python -c "import sys, json; print(json.load(sys.stdin)['primaryMasterKey'])")
+COSMOS_DB_PASSWORD=$(curl 'https://management.azure.com/subscriptions/<YOUR SUBSCRIPTION>/resourceGroups/<YOUR RG>/providers/Microsoft.DocumentDB/databaseAccounts/<YOUR ACCOUNT>/listKeys?api-version=2016-03-31' -X POST -d "" -H "Authorization: Bearer $ACCESS_TOKEN" | python -c "import sys, json; print(json.load(sys.stdin)['primaryMasterKey'])")
 ```
 ## Windows security baselines
 [We recommend that you implement an industry-standard configuration that is broadly known and well-tested, such as Microsoft security baselines, as opposed to creating a baseline yourself](/windows/security/threat-protection/windows-security-baselines); an option for provisioning these on your Virtual Machine Scale Sets is to use Azure Desired State Configuration (DSC) extension handler, to configure the VMs as they come online, so they are running the production software.
