java.security.cert.CertPath NetworkData.getCertificateChain()

A CertPath containing the X509 certificates that identify the client; returns null if no such certificates were provided.

The certificates are all java.security.cert.X509Certificate objects.

This method returns a non-null value only if the isTLS method returns true, and the client supplies a certificate using the "identity" stream parameter. A non-null CertPath value contains the certificates, ordered from the self-signed certificate to the peer certificate.
