AWS DynamoDB Encryption In Transit | Overview

Let’s examine AWS DynamoDB encryption in more detail. As a part of our AWS Support Services, Skynats provides answers to all of your questions.

AWS DynamoDB encryption

Extremely dependable storage infrastructure is provided by Amazon DynamoDB, making it perfect for storing mission-critical and important data. Data is redundantly stored on numerous devices dispersed throughout various facilities in an Amazon DynamoDB Region.

Both user data in storage and data traveling between on-premises clients and DynamoDB, as well as between DynamoDB and other AWS resources located in the same AWS Region, are protected by DynamoDB. The purpose of using DynamoDB encryption is to:

  • Data at rest
  • Data in transit
  • Data in use

AWS DynamoDB encryption in transit

Data in transit encryption encrypts private information as it moves to and from DynamoDB. It guarantees that the plaintext data is inaccessible to outside parties, including AWS. Data in transit will be encrypted using the software library known as the DynamoDB encryption client. Under the terms of the Apache 2.0 license, the encryption client is free.

The DynamoDB encryption client will enable the user to encrypt and sign items as they are added to the table. Once the data has been retrieved, users can use it to verify and decrypt the information. An alternative name for this method is client-side encryption. Majority of Amazon DynamoDB’s features, such as global tables, are supported; however, to use the encryption client with older versions of global tables, we might need to make some configuration changes.

The DynamoDB encryption client enables secure implementations by allowing each item in a table to have its attribute values encrypted using a different encryption key. Additionally, by signing the items, we can guard against unauthorized changes, such as the addition or deletion of attributes or the swapping of encrypted values.

We can use encryption keys generated by a variety of custom cryptography services, including AWS CloudHSM and AWS Key Management Service, when using the DynamoDB Client (AWS KMS).

Python and Java currently support DynamoDB encryption client libraries. Because it is implemented in multiple programming languages, we can encrypt data with the Java client and decrypt it with the Python client.

On the other hand, the Amazon S3 Encryption Client and the AWS Encryption SDK are incompatible with the DynamoDB Encryption Client. As a result, we are unable to encrypt using one client-side library and decrypt using a different one.


A highly dependable storage infrastructure for mission-critical and primary data storage is offered by AWS DynamoDB encryption. Additionally, it offers protection for both data in transit and data at rest. In this article, we provide relevant information from our Technical support team regarding AWS DynamoDB encryption.
