Servers should be able to upgrade to stronger keys over time ("key rotation"), which replaces the public key in the certificate with a new one.

Unfortunately, now the client app has to be updated due to what is essentially a server configuration change.

The focus of this section is the second part: making sure the server you are talking to presents the right certificate.

When it doesn't, you'll typically see an error like this:

Returns the principal that was sent to the server during handshaking. If not overridden, it will default to returning the X500Principal of the end-entity certificate that was sent to the server for certificate-based ciphersuites or, return null for non-certificate based ciphersuites, such as Kerberos. Returns an X500Principal of the end-entity certificate for X509-based cipher suites, and Kerberos Principal for Kerberos cipher suites. Returns the server's principal which was established as part of defining the session. If not overridden, it will default to returning the X500Principal of the server's end-entity certificate for certificate-based ciphersuites, or throw an SSLPeer Unverified Exception for non-certificate based ciphersuites, such as Kerberos.

Returns the server's certificate chain which was established as part of defining the session.

It's possible that an application might use SSL incorrectly such that malicious entities may be able to intercept an app's data over the network.

To help you ensure that this does not happen to your app, this article highlights the common pitfalls when using secure network protocols and addresses some larger concerns about using .

Https URLConnection Input Stream(Https URLConnection Impl.java:271) One reason this can happen is due to a server configuration error.

IOException: Hostname 'example.com' was not verified at http.

Http Connection.verify Secure Socket Hostname(Http Connection.java:223) at http. Http URLConnection Response(Http URLConnection Impl.java:282) at http.

When multiple certificates are available for use in a handshake, the implementation chooses what it considers the "best" certificate chain available, and transmits that to the other side.

This method allows the caller to know which certificate chain was actually sent.

This is especially problematic if the server is not under the app developer's control, for example if it is a third party web service.
