The Centralized Signator service of the AOC Consortium will be updated next April 26, 2023 in order to increase the security of the signatures it generates. Following security recommendations, the service's default hashing algorithm will change from SHA-1 to SHA-2.
This change was already applied, a few months ago, to the PREPRODUCTION environment so that the integrators could validate it. It is very important that you test in this environment because SHA-2 incompatibilities with operating systems and applications have been detected.
Signatures generated up to this date with SHA1 will continue to be valid.
You will find instructions for conforming to the SHA2 algorithm this article.
If you have any questions, you can contact ours Customer Service Center.
