Why Syspeace uses SHA-2 and important notes for Windows Server 2003 users

As of today, September 2, 2016, we have switched to using a SHA-2 SSL/TLS certificate for this web site, our Syspeace Licenses site used to manage and purchase licenses, as well as our backend server used by the Syspeace application. The SHA-2 hash algorithm is a newer and more robust hash algorithm than SHA-1, as previously used – SHA-1 has been globally deprecated for years, and since the beginning of 2016, no new SHA-1 certificates are issued by trusted Certificate Authorities.

SHA-2 is unsupported in Windows Server 2003 and 2003 R2, leading to the following:

  • Syspeace users on Windows Server 2003 will have to upgrade to a special Windows Server 2003 variant of Syspeace 2.6 that uses a self-signed, privately issued SHA-1 certificate to maintain the current functionality. This version, along with a special information page, has been available for weeks and we have contacted the affected Syspeace users with this information.
  • Access to any of the affected web sites may be restricted from the versions of Internet Explorer compatible with Windows Server 2003. We recommend using an alternative browser like Chrome or Firefox, or a different computer.

For these reasons, the renewal to the new certificate was done at the last moment (our previous certificate expires on September 3, 2016), to give our customers more time to adjust.
