If this function returns true, you must input the signature when calling <a class="el" href="class_p_k___verifier.html#_verifier_with_recovery_templatea15">NewVerificationAccumulator()</a>. Otherwise, you must input the signature when calling <a class="el" href="class_p_k___verifier.html#_verifier_with_recovery_templatea16">Verify()</a>.
