Update of Copernicus Sentinel-2 Level-1C and Level-2A Processing Baselines

03 June 2021

Within the next couple of weeks, the Copernicus Sentinel-2 products will be subject of a minor update in the ‘manifest.safe’ file packaged at the root of every product bundle. In the 'manifest.safe' file, while every other file included in the product structure is listed together with a corresponding checksum code to verify its integrity, the algorithm used to derive the checksum will evolve from the current MD5 algorithm to the more resilient SHA3 (Secure Hash Algorithm 3) with SHA3-256 instance hash codes.

The Sentinel-2 products featuring this update will tag the new Processing Baselines 03.01 for both Level-1C and Level-2A products.

We invite you to already verify the compatibility of this evolution with your applications using sample products made available for the purpose:

A separate communication will follow with the detailed schedule of this upcoming transition.
