The code then implements the receive loop we discussed in
Chapter 27
.
The difference is
that it uses the RESTEasy
org.jboss.resteasy.jose.jwe.JWEInput
class to decrypt the
received message. A
JWEInput
instance is initialized with the received text message. The
JWEInput.decrypt()
method decrypts the JWE with the shared secret. The
readContext()
method extracts the decrypted bytes into a
String
object that we can output to the console. If
the message is not a JWE or if the wrong secret is used, then the original received text mes-
sage is outputted to the console.
Let's now take a look at how sending a message has changed:
