Use SHA1 hashes for certificates URL #2896
Description
Is your feature request related to a problem? Please describe.
The current certificates link (although requiring the user ID) allows anyone to publicly scan through all certificates and collect personal information with some level of freedom.
Describe the solution you'd like
Use a hash to identify certificates
- add a hash column to the certificate table
- if existing certificates, use the certificate ID to fill the hash column the first time, so previous reference links continue to match the certificate
- make sure the link tag and the QR tag in the certificate edition now use the link with a hash
