All Known Implementing Classes:

public interface BlindSigningKey

extends SigningKey

This interface is implemented by keys that can be used to create and validate blind signatures on fingerprints of data.

Obviously blind signatures should be used with care since you do not know what is being signed. The key used for blind signatures should be created specifically for one purpose and never be used for anything else.
