Using the runmqakm commands and an HSM (but not strmqikm).

I tried to use strmqikm but it gave an exception.

You can use some of the runmqakm commands you know and love, to access a certificate with an HSM. For example

The command to list the database available to the runmqakm command,

runmqakm -keydb -list -crypto /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so

Gives

/usr/lib/x86_64-linux-gnu/opensc-pkcs11.so : UserPIN (mytoken)

You can then use the token label UserPIN (mytoken) and password to use the key store, for example

runmqakm -cert -list all -crypto /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so
-tokenlabel “UserPIN (mytoken)” -pw 12345678

gives

Certificates found
* default, - personal, ! trusted, # secret key
-	my_key3

and

runmqakm -cert -details -crypto /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so
-tokenlabel “UserPIN (mytoken)” -pw 12345678
-label my_key3

displays the details of the certificate with label my_key3.

If the -tokenlabel was wrong or the -pw was wrong, I got the unhelpful messages

  • CTGSK3026W The key file “pkcs11” does not exist or cannot be read.
  • CTGSK2137W The label does not exist on the PKCS#11 device.

Create your certificate request

The following command create a new RSA private-public key pair and a PKCS10 certificate request. The documentation for runmqakm says it supports RSA. If you want to use an Elliptic Curve you will need to use an alternative method, for example openssl.

runmqakm -certreq -create -crypto /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so
-tokenlabel “UserPIN (mytoken)” -pw 12345678
-dn “cn=colin,o=SSS” -file runmq.csr -label runmqlab -size 1024

Sign it

openssl ca -config openssl-ca-user.cnf -policy signing_policy -md sha256 -cert carsa1024.pem -keyfile carsa1024.key.pem -out runmq.pem -in runmq.csr

Store it back into the HSM keystore

I could not get the runmqakm command to receive the signed certificate and store it into the HSM keystore.

runmqakm -cert -receive -crypto /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so -tokenlabel “UserPIN (mytoken)” -file runmq.pem -pw 12345678

It failed with

CTGSK3034W The certificate request created for the certificate is not in the key database.

I could use

openssl x509 -inform pem -outform der -in runmq.pem -out runmq.der
pkcs11-tool –write-object runmq.der –type cert –label “runmqlab” -l –pin 12345678

The openssl command converts the file from .pem format, to .der format as .der format is required by pkcs11-tool.

Using strmqikm – the theory

If you want to use the strmqikm GUI, you have to configure the java.security file. For example edit /opt/mqm/java/jre64/jre/lib/security/java.security and add the next security.provider in the list.

security.provider.12=com.ibm.crypto.pkcs11impl.provider.IBMPKCS11Impl /home/colinpaice/mq/nitrokey.cfg

Where /home/colinpaice/mq/nitrokey.cfg is the configuration file, with

name = nitrokey
library = /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so
slot=0

You can then use Ctrl+O, which brings up a pop up with “Key database type”. In this list should be PKCS11Config, if not check your java.security file. Select this, leave File Name and Location empty, and click “OK”. It pops up “Open Cryptographic Token” with the “Token Label” value taken from the configuration file name = nitrokey. This is strange as the runmqakm command uses a TokenLabel of “UserPIN (mytoken)”.

In practice…

I then got an exception java.lang.RuntimeException: PKCS11KeyStore.java: findSigner(): Failure while executing cobj.getX509Certificate(certFactory, session), and strmqikm ended.
