Messages

TLS-Attacker supports multiple messages which can be used to form Workflows. Each key exchange message is implemented as an individual message. Note: Since a workflow is a predefined list of Actions (which contain messages) some workflows will not always succeed. TLS-Attacker will never add Messages on its own to your custom workflow. This may result in failing Handshakes depending on the negotiated parameters.

The following messages are currently Implemented:

• Certificate
• CertificateVerify
• CertificateRequest
• ClientHello
• HelloVerifyRequest
• DHClientKeyExchange
• DHEServerKeyExchange
• ECDHClientKeyExchange
• ECDHEServerKeyExchange
• Finished
• RSAClientKeyExchange
• ServerHelloDone
• ServerHello
• Alert
• Application
• ChangeCipherSpec
• SSL2ClientHello
• SSL2ServerHello
• UnknownMessage
• UnknownHandshakeMessage
• HelloRequest
• Heartbeat
• EncryptedExtensionMessage
• HttpsRequest
• HttpsResponse
• HelloRetryRequest

You can use these Messages in your custom XML Workflows. For a list of all available Fields check the code of the class or execute the message once and look at the resulting XML output.
