Hi!

Curious, if i there tool\site with wich i could verify for example 1 of 100 physically printed books?

Each one book - unique public key (100 books = 100 keys, printed on backside of it) wich could be verify by one private key

It just and idea in mind, but, maybe there any ready solution? Many public keys chain-linked with one master key - are just for example

Thank you

Take your single public key, encrypt 100 unique values with it, end up with 100 unique cipher texts, all decryptable with your private key.
