Availability of SHA-256 certificates: 14 October 2014
 
We’re pleased to announce an agreement has been reached between TERENA and Comodo which will enable customers to obtain SHA-256 certificates.
 This is available with immediate effect and all certificates obtained from the service will be by default SHA-256.
 
As a result of the deprecation of SHA-1 certificates expiring in 2017 by the all the major web browsers,
 all customers who obtained 3-year certificates in 2014 are advised to replace them over the next few months.
To help make this process easier for you, we are automatically crediting affected accounts to enable the replacement of
 these certificates at no cost.
 
We apologise for any inconvenience that this issue has caused our customers and thank you for your patience.
 
If you have any questions or queries, please contact the Janet Service Desk on : 0300 300 2212 or email certificates@ja.net.
 
Please be aware that the two intermediate certificates used to sign the new SHA-256 certificates are different to those used
 to sign SHA-1 certificates. When you replace certificates with SHA-256 please make sure you also install these 
other two intermediates, namely TERENASSLCA2 and USERTrustRSAAddTrustCA. The root certificate, AddTrustExternalCARoot, remains the same.
 
To keep up with any service announcements please join the JCS Community Group.
