CAPLfunctionOnObservedAndDecryptedTlsApplicationData

OnObservedAndDecryptedTlsApplicationData

Valid for: CANoe DE • CANoe4SW DE

Function Syntax

void OnObservedAndDecryptedTlsApplicationData(IP_Endpoint sourceEndpoint, IP_Endpoint destinationEndpoint, byte data[], dword vlanIds[], dword applicationChannel)

void OnObservedAndDecryptedTlsApplicationData(IP_Endpoint sourceEndpoint, IP_Endpoint destinationEndpoint, byte data[], dword vlanIds[], dword applicationChannel, EthernetPort hardwareChannel)

Description

If the CAPL program implements this callback, it is called when observed and decrypted TLS application data is available. The application channel allows to further select in the CAPL code, in which application data one is interested. In the case of an application-channel-based access OnObservedAndDecryptedTlsApplicationData with 5 parameters needs to be used. In contrast, with network-based access OnObservedAndDecryptedTlsApplicationData with 6 parameters, including the hardware channel, is required. The network access can be set in the CANoe options Bus Systems/Protocols, Ethernet. The data length can be retrieved with elcount(data) in the CAPL code.

Parameters

• sourceEndpoint: Address and port to which the source socket is connected.
• destinationEndpoint: Address and port to which the destination socket is connected.
• data: Observed and decrypted TLS application data.
• vlanIds: vLAN Ids
• applicationChannel: ethernet application channel.
• hardwareChannel: ethernet hardware channel.

Return Values

Example

void OnObservedAndDecryptedTlsApplicationData(IP_Endpoint sourceEndpoint, IP_Endpoint destinationEndpoint, byte data[], dword vlanIds[], dword applicationChannel, EthernetPort hardwareChannel)
{
  char endpointStr[100];

  sourceEndpoint.PrintEndpointToString(endpointStr);
  if (sourceEndpoint.Address.IsIPv4Address() == 1)
  {
    write("Observed IPv4 package from src endpoint = %s on network %s with %d bytes of application data", endpointStr, hardwareChannel.networkname, elCount(data));
  }
  else if (sourceEndpoint.Address.IsIPv6Address() == 1)
  {
    write("Observed IPv6 package from src endpoint = %s on network %s with %d bytes of application data", endpointStr, hardwareChannel.networkname, elCount(data));
  }
