Government Gateway

HMRC previously let you know about 3 Live tests organised by the Government Gateway Team in preparation for the withdrawal of SHA 1 Digital Certificates. These previous tests took place on Tuesday 12 April 2016, Tuesday 26 April 2016 and Tuesday 17 May 2016. These Live tests were held to establish and ensure that customers will still be able to connect to the Government Gateway when the changes have been made. The date for this change is 25 May 2016. From this date all Government Gateway websites certificates will use SHA-2 certificates. This mandated change is taking place in the Government Gateway as a direct result of IT security industry changes being made worldwide in regards to Secure SHA certification.
