Sun Java System Message Queue 3.7 UR1 Administration Guide


To encrypt messages sent between clients and broker, you need to use a connection service based on the Secure Socket Layer (SSL) standard. SSL provides security at the connection level by establishing an encrypted connection between an SSL-enabled broker and client.

To use an SSL-based Message Queue connection service, you generate a public/private key pair using the Key Tool utility (imqkeytool). This utility embeds the public key in a self-signed certificate and places it in a Message Queue key store. The key store is itself password-protected; to unlock it, you must provide a key store password at startup time, specified by the imq.keystore.password property. Once the key store is unlocked, a broker can pass the certificate to any client requesting a connection. The client then uses the certificate to set up an encrypted connection to the broker.

The imq.audit.enabled broker property controls the logging of audit records to the Message Queue broker log file; see Audit Logging for more information.
