How to pull out the inbound certificate of a HTTPS endpoint in Mule

Question

Using Mule CE 3.5 I need to inspect the certificate provided with an inbound response.

I have a HTTPS endpoint configured and I've tried attaching a custom transformer to the response but it receives a ReleasingInputStream that contains the information I need but doesn't appear to expose it publicly. See the private HttpMethod property here: http://opensourcejavaphp.net/java/mule/org/mule/transport/http/ReleasingInputStream.java.html

I'm assuming there must be a simpler way of doing this. Are there any other ways of achieving this?

What you are looking for should be in the PEER_CERTIFICATES outbound property on the Mule message.

See: https://github.com/mulesoft/mule/blob/mule-3.5.0/transports/http/src/main/java/org/mule/transport/http/HttpsMessageProcessTemplate.java#L44
