# Prerequisites
<a name="producer-sdk-cpp-prerequisites"></a>

Before you set up the C\+\+ producer SDK, ensure that you have the following prerequisites: 
+ **Credentials:** In the sample code, you provide credentials by specifying a profile that you set up in your AWS credentials profile file. If you haven't already done so, first set up your credentials profile. 

  For more information, see [Set up AWS Credentials and Region for Development](https://docs.aws.amazon.com//sdk-for-java/v1/developer-guide/setup-credentials.html).
+ **Certificate store integration:** The Kinesis Video Streams producer library must establish trust with the service it calls. This is done through validating the certificate authorities (CAs) in the public certificate store. On Linux-based models, this store is located in the `/etc/ssl`/ directory. 

  Download the certificate from the following location to your certificate store:
