Interface ContentVerifier

public interface ContentVerifier
A streaming verifier of a signature over to-be-signed content.

Callers write the exact to-be-signed DER to contentStream() and then call verify(byte[]) with the signature to check. Verification is performed against a public key that was fixed when the verifier was created (see the zeroecho.pkix factory methods).

Lifecycle

An instance is single-use and need not be thread-safe.
