Message history encryption?

[jplock]

Do you want to demonstrate how to encrypt the message history in DynamoDB in this example?

Hi Justin - The DynamoDB table is already encrypting data at-rest as the SSE specification is set to True.

For double encryption, you can specify a KMS key ID when calling LangChain's DynamoDBChatMessageHistory method in the agent's chat class.
