Practical mastering IBM MQ basics

When using SSL/TLS, once you decide on a CipherSpec, you need to prepare a digital certificate (server certificate) that is compatible with that CipherSpec. There are three main types of digital certificates.

In this verification work, we created an intranet CA and created an RSA public key/self-signed CA(root) certificate, which can be used as is for all types. The server(CA signed) certificate was created with an RSA public key/RSA signature. This type of certificate can be used with Type 2 and Type 3 of the above CipherSpecs types, where both the "public key" and "digital signature encryption algorithm" are RSA. In order to use Type1 CipherSpec, it is necessary to prepare a certificate whose "public key" type is "elliptic curve" and "digital signature encryption algorithm" is "ECDSA".

In this article, we will explain the work procedure when using Type 1 CipherSpec. Except for the method of creating a certificate request, the procedure is almost the same as before, so detailed explanation is omitted, so please refer to the previous explanation if necessary. The following is an example of a client connection, but the idea is basically the same for a server-to-server connection.

Creating a CSR to use Type 1 CipherSpec (GSKit)

If you have never performed the procedure for using SSL/TLS in the client connection up to the previous time, perform the procedure up to just before "Create Certificate Signing Request(CSR) (Windows, Linux)" in "SSL/TLS setup on the client (to create CSR) (GSKit)".

To use Type 1 CipherSpec (ECDHE_ECDSA_ *), you must create a certificate request with the Elliptic Curve ECDSA signing algorithm specified for "-sig_alg" in the runmqakm command. Here, try using EC_ecdsa_with_SHA512. For the elliptic curve algorithm, the possible key size values are 256, 384, or 512, and the default elliptic curve key size depends on the signing algorithm: 256 for SHA256, 384 for SHA384, and 512 for SHA512. If any other key size is specified, GSKKM_ERR_CRYPTO_UNSUPPORTED_MODULUS_SIZE will occur and CSR creation will fail.
*The following is an example of Windows, but the same applies to Linux, and it is specified in one line. For DN, specify the contents for each server.

-certreq: The target of the command is a certificate request
-create: Create a certificate request
-db filename: Specifies the fully qualified file name of a CMS key database.
-pw password: Specifies the password for the CMS key database.
-label label: Specifies the key label attached to the certificate. The label is either the value of the CERTLABL attribute, if it is set, or the default ibmwebspheremq with the name of the queue manager all in lowercase.
-dn: distinguished_name: Specifies the X.500 distinguished name enclosed in double quotation marks. At least one attribute is required.
-size key_size: Specifies the key size.
-file filename: Specifies the file name for the certificate request.
-sig_alg hashalgorithm: Specifies the hashing algorithm used during the creation of a certificate request. This hashing algorithm is used to create the signature associated with the newly created certificate request.

Make sure that the certificate request is created as expected.

*The Key Size is displayed as 522, but to be exact, there is no size of 512 for the elliptic curve, so there is no problem. Even if you omit the specification of "-size 512", if you specify EC_ecdsa_with_SHA512, the Key Size will be 522 by default.

Creating a CSR to use Type 1 CipherSpec (Openssl)

For Openssl, the procedure for creating a CSR is quite different from RSA. For HPE NonStop, follow the steps described here.

Certificate verification

Please refer to the following to verify the certificate. See "Certificate Verification" for more information.

Check the symmetry of private and public keys

For elliptic curves, both Openssl / GSKit only check the public key. Compare the hash values in each file and make sure they are all the same.

*CA signature certificate(server certificate) >openssl x509 -in newcerts\03.pem -modulus -noout | openssl md5 (stdin)= 7afc15dd6126715f4bd86b16741256e7 *Certificate request(CSR) >openssl req -in ..\..\clientssl\key.csr -modulus -noout | openssl md5 (stdin)= 7afc15dd6126715f4bd86b16741256e7

Add CA(root) certificate to key repository(GSKit)

This procedure has already been performed in "Add CA(root) certificate to key repository(GSKit)" when testing server-to-server connections and client connections. If not, refer to them.

Receive personal certificate to key repository(GSKit)

This procedure is also the same as the procedure of "Receive personal certificate to key repository(GSKit)" performed for server-to-server connection and client connection, so please refer to those procedures as well.

Add a CA-signed certificate(personal certificate) to the key repository for the client machine. Importing a personal certificate must always be in the key repository that created the CSR.

Add the personal certificate using the runmqckm command.

>cd ...\clientssl >copy ..\openssl\winca\newcerts\03.pem PL921WCB.pem >runmqckm -cert -receive -file PL921WCB.pem -db key.kdb -pw PL921WCpass -format ascii 5724-H72 (C) Copyright IBM Corp. 1994, 2020. Validation successful. >

Creating and deploying SSL/TLS related files(Openssl)

This work is the same as the work done for server-to-server connection, so please refer to that as well.
Place the related file created by the specified procedure in the location specified by the SSLKEYR attribute of the queue manager.

Concatenate the CA-signed server certificate and key file

Combine the CA-signed server certificate and key file into one file as follows.
In the example below, "PL81NB" is specified as CERTLABL.

$ pwd .../openssl/nsca/PL81N_C $ cp -p ../newcerts/02.pem . $ cat 02.pem PL81Nec.key > PL81NB.pem

We will also verify the combined files just in case.

$ openssl x509 -subject -issuer -noout -in PL81NB.pem subject=C = AU, ST = Sydney, O = Pulsar Integration PL81NA Inc., CN = www.sd.pulsarintegration.PL81Nec.com issuer=C = AU, ST = Sydney, O = Pulsar Integration SD Inc., CN = www.sd.pulsarintegration.com, emailAddress = support@sd.pulsarintegration.com

$ amqrsslc -s PL81NB Enter password for Keystore PL81NB : PL81Necpass Stashed the password in file PL81NB.sth or $ echo PL81Necpass | amqrsslc -s PL81NB Stashed the password in file PL81NB.sth $ ls -l *.sth .... 128 Aug 27 11:47 PL81NB.sth

*Option descriptions
-s : Key store path

Place created files in the SSLKey repository

Check the queue manager's SSLKEYR property for the location of the key repository.

Testing a client connection using TLS(MQCD)

Try to test the connection using the channel definition structure (MQCD). For the procedure of connection test using CCDT, refer to the explanation in the previous client connection.

Creating a server-side TLS connection definition

Create a server connection channel(SVRCONN) on the server side with the following command.

$ mqpcf mqsc -qm PL81N -s "def chl(PL81N.MQICHL.EC) chltype(svrconn) certlabl(PL81NB) SSLCIPH(ECDHE_ECDSA_AES_128_CBC_SHA256)"

Ex. 13.1.1 Performing the Client Connection Using SSL/TLS(MQCD)

Specify the certificate label and CipherSpec on the MQCD. To specify the certificate label (CertificateLabel), it is necessary to use MQCD version 11(MQCD_VERSION_11) or higher. Environment variables other than MQSSLKEYR are unnecessary, so delete them. Create a client connection with specifying SSLCipherSpec and CertificateLabel by the following command.

>set MQSERVER=
>set MQCHLTAB=
>set MQCHLLIB=
>set MQSSLKEYR=C:\...\clientssl\key
>mqpgfc -qm PL81N -q LQ1 MQGMO_WAIT MQWI_UNLIMITED -x xxx.xxx.xxx.xxx(xxxx9) -ch PL81N.MQICHL.EC -cl PL921WCB -cs ECDHE_ECDSA_AES_128_CBC_SHA256 MQCD_VERSION_11
