In 2016 the AAF published three metadata documents:
https://md.aaf.edu.au/aaf-metadata.xml – Containing all AAF subscribers
https://md.aaf.edu.au/aaf-edugain-metadata.xml – Containing IdP and SP which have been approved for consumption by AAF subscribers from the global eduGAIN metadata source
https://md.aaf.edu.au/aaf-edugain-export-metadata.xml – Containing AAF subscribed IdP and SP which have been approved for publishing to the global eduGAIN metadata source
All of these metadata documents are signed by the AAF.
Subscribers must use the public key available at https://md.aaf.edu.au/aaf-metadata-certificate.pem to verify metadata documents whenever they are retrieved.
To confirm that you have obtained the correct key ensure the file you have downloaded conforms to the following:
