Down in Bulgaria too.

Try looking into SSI (self-sovereign identity) and verifiable credentials - the use-case you are referring to.

Thanks for the pointers. Are first glance, SSI seem to be mainly Blockchain based, which we diverted from to be able to have easy on premise deployments. Verifiable credentials look interesting, but need to check usability. We want our solution to be very easy to use.

Pretty cool little tool.

It would be even cooler if it highlighted matched keys while typing.
