the class SignerInfo method verifyWithAuthenticatedAttributes.

/**
 * Verifies a SignerInfo with authenticated attributes.  If authenticated
 * attributes are present, then two particular attributes must
 * be present: <ul>
 * <li>PKCS #9 Content-Type, the type of content that is being signed.
 *      This must match the contentType parameter.
 * <li>PKCS #9 Message-Digest, the digest of the content that is being
 *      signed. This must match the messageDigest parameter.
 * </ul>
 * After these two attributes are verified to be both present and correct,
 * the encryptedDigest field of the SignerInfo is verified to be the
 * signature of the contents octets of the DER encoding of the
 * authenticatedAttributes field.
