Obtain a certificate chain.
For more information about obtaining a certificate chain, see Certificate chains. To prepare a Java KeyStore JKS or PKCS #12 key store with an appropriate certificate chain and private key, use the manage-certificates tool. We also recommend that you create a trust store that the server can use.
Configure the key and trust manager providers.
For more information, see Configuring key and trust manager providers.
