A National Authentication Service for Health Public Key Infrastructure or NASH PKI Certificate is used by healthcare organisations to maintain access to important digital health services such as electronic prescribing, My Health Record, secure messaging and Healthcare Identifiers (HI).

The security of people’s health information is critical, which is why healthcare organisations must have a current NASH certificate to continue using digital services.

NASH is used by healthcare provider organisations and supporting organisations to authenticate and securely access digital health services, digitally sign documents and other transactions, and encrypt health information for secure exchange.

Note that support for NASH SHA-1 and Medicare PKI expired on 24 March 2024 and software had to be configured to use a NASH SHA-2 certificate by this date.

Watch the video below or visit the NASH website to learn the steps to renew your NASH PKI certificate.

Note the renewal of Medicare PKI certificate is a separate process to NASH PKI renewal and your organisation may likely need to follow the guidelines for Medicare PKI certificate transition.
