Package org.drasyl.peer.connection.message

Class SignedMessage

java.lang.Object

org.drasyl.peer.connection.message.SignedMessage

All Implemented Interfaces:

Signable, Message

public class SignedMessage
extends Object
implements Message, Signable

Represents a container with a signature for the payload. The signature must be valid under the supplied public key.
The signature does not give any guarantees about the logical integrity of the payload, but only guarantees that the payload was sent by the identity with the public key (as the last node in a relay chain).

SignedMessage

public SignedMessage(Message payload,
                     CompressedPublicKey kid)

SignedMessage

public SignedMessage(Message payload,
                     CompressedPublicKey kid,
                     Signature signature)

Method Detail

getPayload

public Message getPayload()

getKid

public CompressedPublicKey getKid()

writeFieldsTo

public void writeFieldsTo(OutputStream outstream)
                   throws IOException

Description copied from interface: Signable

Write any content into the passed output-stream to have them included in the signing process.

Only use this with the default-implementation of Signable.getSignableBytes()

Specified by:

writeFieldsTo in interface Signable

Parameters:

outstream - an outputstream to write to

Throws:

IOException

getSignature

public Signature getSignature()

Description copied from interface: Signable

Returns the signature this signable object was signed with.

Specified by:

getSignature in interface Signable

setSignature

public void setSignature(Signature signature)

Description copied from interface: Signable

Signs the object with the specified signature. After this method was invoked subsequent calls to Signable.getSignature() should return a Signature object that is equal to the specified signature.

Specified by:

setSignature in interface Signable

getId

public MessageId getId()

Specified by:

getId in interface Message

Returns:

the unique id of this message. Each message generates a random id when it is created.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
