   # cat ssl_pw_file
   password
   
   # certutil -S -d . -n qrootCA -s "CN=qrootCA" -t "CT,," -x -m 1000 -v 120 -f ssl_pw_file
   # certutil -S -n "fully-qualified-server-name.com" -s "CN="fully-qualified-server-name.com -c qrootCA -t ",," -m 1001 -v 120 -d . -f ssl_pw_file
   # certutil -S -n client -s "CN=client" -t ",," -m 1005 -v 120 -c qrootCA -d . -f ssl_pw_file
   # pk12util -d . -o client.p12 -n client
   Enter Password or Pin for "NSS Certificate DB":
   Enter Password or Pin for "NSS Certificate DB":
   Enter password for PKCS12 file:
   Re-enter password:
   pk12util: PKCS12 EXPORT SUCCESSFUL
   # openssl pkcs12 -in client.p12 -out client.pem -nodes -clcerts
   Enter Import Password:
   MAC verified OK

2. Verify that the files exist:

   # ls

   # scp -r qpid_nss_db root@other-broker.com:/var/lib/qpidd
   # chown -R qpidd:qpidd qpid_nss_db

2. Verify the files and their permissions:

   # ll
   total 89896
   -rw-r-----. 1 qpidd qpidd        0 Jul 16 06:27 lock
   -rw-r--r--. 1 qpidd qpidd 91989014 Nov  1 06:52 qpidd.log

  auth=no
  ssl-cert-db=/var/lib/qpidd/qpid_nss_db

Procedure 8.5. Start the broker

• Start the broker and verify that it is listening on the SSL port:

  # service qpidd restart
  Stopping Qpid AMQP daemon:             [  OK  ]
  Starting Qpid AMQP daemon:             [  OK  ]
  
  # netstat -nap | grep qpidd
  tcp        0      0 0.0.0.0:5671                0.0.0.0:*                   LISTEN      25184/qpidd
  tcp        0      0 0.0.0.0:5672                0.0.0.0:*                   LISTEN      25184/qpidd
  tcp        0      0 :::5671                     :::*                        LISTEN      25184/qpidd
  tcp        0      0 :::5672                     :::*                        LISTEN      25184/qpidd
  

Procedure 8.6. Create a folder to export onto Windows machines

1. Execute the following instructions to:
   • Create a folder to export onto Windows machines
   • Create a new password file in .txt format
   • Export certification authority certificate to .cer format
   • Export client certificate to .pfx format

   # mkdir windir
   # echo password2 > windir/win_pw_file.txt
   # cat windir/win_pw_file.txt
   password2
   # certutil -L -d qpid_nss_db -n qrootCA -f ssl_pw_file -a > windir/qrootCA.cer
   # pk12util -d qpid_nss_db -n client  -k qpid_nss_db/ssl_pw_file -w windir/win_pw_file.txt -o windir/client.pfx
           pk12util: PKCS12 EXPORT SUCCESSFUL

2. Verify that the files exist:

8. Click on Next.
9. Type a password from win_pw_file.txt (password2 in our case).
10. Choose Certificate Store Personal and save the console settings.
11. Modify broker configuration to require client authentication and restart it .
12. Set up environment variables:

    >set QPID_SSL_CERT_STORE=My
    >set QPID_SSL_CERT_NAME=client

13. Test it by sending a message:

    >C:\qpid_VS2008\bin\Release>spout.exe --broker broker-server.com:5671 --connection-options {transport:ssl,sasl-mechanisms:EXTERNAL} amq.topic
    

Procedure 8.12. Specify Certificate via Environment

1. Set up environmental variables on the Windows machine:

   >set QPID_SSL_CERT_FILENAME=<path_to_the_client.pfx>
   >set QPID_SSL_CERT_PASSWORD_FILE=<path_to_the_win_pw_file.txt>
   >set QPID_SSL_CERT_NAME=client

   For example:

   >C:\qpid_VS2008\bin\Release>set QPID_SSL_CERT_FILENAME=C:\windir\client.pfx
   
   >C:\qpid_VS2008\bin\Release>set  QPID_SSL_CERT_PASSWORD_FILE=C:\windir\win_pw_fil
   e.txt
   
   >C:\qpid_VS2008\bin\Release>set QPID_SSL_CERT_NAME=client

2. Test it by sending a message:

   C:\qpid_VS2008\bin\Release>spout.exe --broker broker-server.com:5671 --connection-options {transport:ssl,sasl-mechanisms:EXTERNAL} amq.topic
