                 Using SSL
                 =========

SSL support for Qpid-C++, based on Mozilla's Network Security Services
library, is provided as two loadable modules: one for the client
(sslconnector.so), one for the broker (ssl.so). Either these libraries
should be present in the relevant module directory or the
'load-module' option (or QPID_LOAD_MODULE environment variable) is
used to ensure they are loaded.

Broker side SSL Settings (note you can get these by qpidd --help
providing the ssl.so module is loaded):

SSL Settings:
  --ssl-use-export-policy              Use NSS export policy
  --ssl-cert-password-file PATH        File containing password to use for
                                       accessing certificate database
  --ssl-cert-db PATH                   Path to directory containing certificate
                                       database
  --ssl-cert-name NAME (thinkpad)      Name of the certificate to use
  --ssl-port PORT (5671)               Port on which to listen for SSL
                                       connections
  --ssl-require-client-authentication  Forces clients to authenticate in order
                                       to establish an SSL connection


The first four of these are also available as client options (where
they must either be in the client config file or set as environment
variables e.g. QPID_SSL_CERT_DB).

To run either the broker or client you need ssl-cert-db-path to point
to the directory where relevant certificate and key databases can be
found.

Certificate databases are set up using certutil (included in the
nss-tools package on fedora). See the NSS site for examples[1] and
full details[2].

For a simple testing you can set up a single db with a single self
signed certificate. E.g (with myhost and mydomain replaced by the
hostname and domainname of the machine in question respectively):

    mkdir test_cert_db
    certutil -N -d test_cert_db -f cert.password
    certutil -S -d test_cert_db -n "myhost.mydomain" \
             -s "CN=myhost.mydomain" -t "CT,," -x \
             -f cert.password -z /usr/bin/certutil

Here cert.password is a file with a password in it that will be needed
for accessing the created db.

The daemon can then be started with something like the following:

./src/qpidd --auth no --load-module src/.libs/ssl.so \
            --ssl-cert-db ./test_cert_db \
            --ssl-cert-password-file ./cert.password \
            --ssl-cert-name myhost.mydomain

then for client set:

QPID_LOAD_MODULE=./src/.libs/sslconnector.so
QPID_SSL_CERT_DB=./test_cert_db

and run e.g.

./src/tests/perftest --count 10000 -P ssl --port 5671 \
                     --broker myhost.mydomain
