Imports

java.io.ByteArrayInputStream, .ByteArrayOutputStream, .IOException, org.bouncycastle.tls.crypto.TlsCrypto, .TlsMAC, .TlsMACOutputStream, org.bouncycastle.util.Arrays

Implements cookie generation/verification for a DTLS server as described in RFC 4347, 4.2.1. Denial of Service Countermeasures.

RFC 4347 4.2.1 additionally recommends changing the secret frequently. This class does not handle that internally, so the instance should be replaced instead.
