TLS 1.2 to become the minimum TLS version for Azure Storage

Published date: November 01, 2023

To respond to evolving technology and regulatory standards, Azure Storage will remove support for TLS version 1.1 and 1.0, and the minimum supported version will be TLS1.2 starting November 1, 2024. TLS 1.2 is more secure and faster than older TLS versions. TLS 1.0 and 1.1 do not support modern cryptographic algorithms and cipher suites.  

This change impacts existing and new storage accounts using TLS 1.0 and 1.1 in all clouds. To avoid disruptions to your applications connecting to Azure Storage, you must migrate to TLS 1.2 and remove dependencies on TLS version 1.0 and 1.1. 

Azure Storage already supports TLS 1.2 which is set as the default. Customers using TLS 1.2 will not be impacted by the removal of support for TLS 1.0 and 1.1. For customers using TLS 1.0 or 1.1, to maintain your connections to Azure Storage, please update your operating systems, development libraries, frameworks, and all other solutions to their latest versions to support TLS 1.2 and update your clients to TLS 1.2 no later than Oct 31st,2024.
