Digital signature certificate repository functions were removed, ending the Controller's statutory duties for public-key database security.

Section 20 concerning the Controller's role as repository has been omitted. Before omission, the Controller was required to retain all Digital Signature Certificates issued under the Act, use hardware, software and procedures secure against intrusion and misuse, observe prescribed standards protecting digital-signature secrecy and security, and maintain a computerised database of public keys accessible to every member of the public.
