# SslData object reference

The SslData object provides access to information established in the TLS handshake with PingAccess.

## Groovy sample

```
// Force TLS client authentication
def certChain = exc?.sslData?.clientCertificateChain
if(certChain && !certChain.isEmpty())
{
  pass();
}
else
{
  fail();
}
```

| List\<String> getSniServerNames()                                     | Returns a list of server name indication (SNI) server\_names sent by the user agent in the TLS handshake. Empty if the user agent did not utilize the SNI TLS extension. |
| List\<java.security.cert.X509Certificate> getClientCertificateChain() | Returns the certificate chain presented by the user agent in the TLS handshake. Empty if the user agent did not utilize TLS client authentication.                       |
