[Valid for](../../../Shared/FeatureAvailability.md):  CANoe DE  •  CANoe4SW DE

## Function Syntax

```plaintext theme={null}
void SCC_TLSHandshakeInd( long Status, long IsServer)
```

## Description

The callback is called when a TLS handshake has been attempted after the SECC Discovery procedure. It is not called, however, if TLS is disabled or TCP was negotiated during SECC Discovery.

To enable TLS, call `SCC_SetTLSEnabled(1)` in CAPL or set the parameter `<UseTLS>` to 1 in the XML configuration file.

## Parameters

* **Status**
  * 1 – TLS handshake has successfully been completed.
  * 2 – TLS handshake has failed. The Write window may contain more details about the cause of the failure.
  * 3 – TLS handshake has most likely failed due to a bad certificate.

* **IsServer**
  * 0 – Callback for EV.
  * 1 – Callback for EVSE.
  * You may usually ignore this parameter as your CAPL code is linked to the EV or EVSE simulation DLL.

## Example

```c theme={null}
void SCC_TLSHandshakeInd( long Status, long IsServer)
{
  WriteLineEx( 0, 0, "SCC_TLSHandshakeInd: status = %i, server = %i", Status, IsServer);
}
