Generally Available: Client-side data integrity protections in Azure Blob Storage

Azure Blob Storage has long supported data integrity validation, starting with MD5 as part of the original HTTP standards and adding CRC64-NVME support in 2019. Today, CRC64-NVME is now integrated into the latest Azure Blob SDKs for .NET, C++, and JavaScript, extending Azure's data integrity protections all the way into client applications. By extending data protection into client applications, customers can verify end-to-end that data written to and read from Blob Storage remains fully intact—byte-for-byte—from the application layer to Azure’s underlying physical storage, using CRC64-NVME checksums. To get started, upgrade to the latest .NET, C++, or JavaScript SDK.
