15.15. A valid certificate may be renewed before its expiry date for the same term as that for which it was issued. The renewal shall be effected by means of a link-up between the holder’s and the registrar’s computer systems within the following time limits:(1) within 2 months of the certificate’s expiry date, where it was issued for one year;
(2) within 4 months of the certificate’s expiry date, where it was issued for 2 years;
(3) within 7 months of the certificate’s expiry date, where it was issued for 3 years;
(4) within 9 months of the certificate’s expiry date, where it was issued for 4 years; or
(5) within 12 months of the certificate’s expiry date, where it was issued for 5 years.
A renewal requires the generation of a new key pair. The new public key that is part of the key pair is automatically sent to the registrar who shall then issue to the holder the certificate relating to the key pair.
