Availability of SHA-256 certificates: 14 October 2014We’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.
Through the Certificate Service portal, organisations can manage their list of Authorised Users. Designated Management Contacts (MC) are now responsible for managing, and keeping up to date, the list of users authorised to request and obtain SSL certificates on behalf of their organisation. Every member of the JCS service will have at least one designated Management Contact, who can add, delete or delegate other verified users to MC status users within their organisation's JCS account.

[If you wish to buy credits using a Purchase Order please just have the PO number available which you enter online at the point of purchase] Please note the "Pay by PO" button is inactivated until the purchase total is £250 or greater.
