Use client secret hashed value

Question

I am following this doc http://docs.identityserver.io/en/release/topics/clients.html which says to create a client with ClientSecrets = "secret".Sha256() and I get the hashed value is of K7gNU3sdo+OL0wNhqoVWhr3g6s1xYv72ol/pe/Unols=

When I try to use the client with the hashed value: options.ClientSecret = "K7gNU3sdo+OL0wNhqoVWhr3g6s1xYv72ol/pe/Unols="; I get an error saying "invalid_client". But If I use options.ClientSecret = "secret"; it works.

How can I use my client with the hashed value?

Answer 1

Hashing is for storage. So when you data store gets compromised, the attacked cannot easily get to the real secrets.

The client sends secrets unhashed.
