This document provides instructions for generating a Certificate Signing Request (CSR) for IMB Websphere MQ using command line. If you are unable to use these instructions for your server, RapidSSL recommends that you contact IBM.
NOTE: Before generating a CSR, you first need to create a key pair for your server. These two items are a digital certificate key pair and cannot be separated. If you lose your public/private key file, forget your password, or generate a new key file, your SSL Certificate will no longer match your private key.
NOTE: SHA-1 Signature Algorithm is the default in GSKit 18.104.22.168 and later. Ikeyman and Ikeycmd (gsk7md) v7 in IHS 6.0.2 and
later support selecting between MD5 and SHA-1 by creating a "ikmuser.properties" in your working directory with a
single line containing just: DEFAULT_SIGNATURE_ALGORITHM=SHA1_WITH_RSA
For more information about selecting signature algorithm in ikeyman please refer to the IBM website
NOTE: To generate a CSR using the IKEYMAN GUI, follow the steps from this link: SO22408
Step 1. Prepare your system
1. Use the gsk7cmd command to create and sign the certificates.
Run the gsk7cmd for a full list of the parameters you can use on the command:
2. Set the DISPLAY environment variable. For example: export DISPLAY=mypc:0.
a) AIX: export JAVA_HOME =/usr/mqm/ssl/jre
b) HP-UX: export JAVA_HOME =/opt/mqm/ssl
c) Linux: export JAVA_HOME =/opt/mqm/ssl/jre
d) Solaris: export JAVA_HOME =/opt/mqm/ssl
Step 2. Create a Keystore
1. Run the following command to create a key repository
gsk7cmd -keydb -create -db filename -pw password -type cms -expire days –stash
runmqckm -keydb -create -db filename -pw password -type cms -expire days –stash
NOTE: On Windows, the key database file (.kdb) is created with read permission for all user IDs,
so it is not necessary to change permissions. On UNIX, .kdb and .sth files are created. Access
permissions for the key database file are set to give access only to the user ID from which you
used iKeyman or iKeycmd.
Step 3. Genera a CSR
NOTE: All certificates that will expire after October 2013 must have a 2048 bit key size.
1. The CSR needs to contain the following Distinguished Name :
2. To generate a CSR, run the following command:
gsk7cmd -certreq -create -db -pw -label -dn "CN=My Queue Manager,O=My Company,C=UK" -
runmqckm -certreq -create -db -pw -label -dn "CN=My Queue Manager,O=My Company,C=UK" -
3. The file you created contains the CSR.
4. Proceed with Enrolment
During the verification process, RapidSSL may need to contact your organization.
Be sure to provide an email address, phone number and fax number that will be
checked and responded to quickly. These fields are not part of the certificate.
Once the SSL certificate has been issued, refer to this link for installation instructions: SO22404
