Returns the identity of the peer which was identified as part of defining the session. Note: This method can be used only when using certificate-based cipher suites; using it with non-certificate-based cipher suites, such as Kerberos, will throw an SSLPeerUnverifiedException.
Note: The returned value may not be a valid certificate chain and should not be relied on for trust decisions.
Note: this method exists for compatibility with previous releases. New applications should use getPeerCertificates()
instead.
