On Tuesday September 18th, we will upgrade the SSL protocol used by our web servers from TLS v1, TLS v1.1 and TLS v1.2 to TLS v1.2 only.
Both TLS v1 and TLS v1.1 are insecure due to the use of the SHA1 and MD5 cyphers.
TLS v1.2 use secured protocols like SHA256 or SHA384 instead of SHA1.
There is no impact on the solution.
Only obsolete web browsers could be impacted with this upgrade. You can test your browser on this page : https://www.ssllabs.com/ssltest/viewMyClient.html
No service disruption is expected during this maintenance.
