As a certification authority recognized under the Electronic Transactions Ordinance of the Hong Kong Special Administrative Region, Digi-Sign Certification Services Limited ("Digi-Sign") is dedicated to implementing the best practices of Public Key Infrastructure.

With technological advancement in cryptography, and in accordance with its Key and Certificate Life Cycle Management Plan laid down in Appendix 3 of its Certification Practice Statement (CPS) (www.dg-sign.com/eng/cps_recognized.htm), Digi-Sign is currently setting up a new CA hierarchy with a new ID-Cert Root CA ("ID-Cert Root CA Cert 3") certificate and a new ID-Cert Signing CA ("ID-Cert Signing CA Cert 3") certificate replacing the existing ID-Cert Root CA Cert 2 and ID-Cert Signing CA Cert 2 certificates before their expiry.

Upon completion of the rollover exercise at around mid June 2018, Digi-Sign will issue new ID-Cert of all classes (except Governmental ID-Cert Class 6, Governmental ID-Cert Class 7, Personal (Banking) ID-Cert Class 10 and Organizational (Banking) ID-Cert Class 11) in a phased manner from this new CA hierarchy using the new ID-Cert Root CA Cert 3 and ID-Cert Signing CA Cert 3 certificates.

Current subscribers of ID-Cert can continue to use their existing ID-Cert until its natural expiry unless otherwise revoked or suspended. From mid June 2018, parties relying on ID-Cert issued under the new CA hierarchy should be able to check the new ID-Cert Root CA certificate, the new ID-Cert Signing CA certificate and the new ID-Cert Certificate Revocation Lists for the verification of digital signature of the subscriber in accordance with Digi-Sign’s CPS.

Meanwhile relying party can contact Digi-Sign Hotline (29178833) for any assistance on any work it may require to support the ID-Cert issued by the Digi-Sign new CA hierarchy.
