IBM cloud HSM

The example below was tested using IBM Cloud HSM 7.0, a FIPS 140-2 Level 3 certified implementation based on the Gemalto SafeNet Luna a750.

Before you start

Make sure that you have:

1. Create, assign, and initialize a new partition

The first step we’ll take is creating an HSM partition, which can be thought of as an independent logical HSM within your IBM Cloud HSM device.

vm$ ssh admin@hsm
[] lunash:>partition create -partition KeylessSSL

          Type 'proceed' to create the partition, or          'quit' to quit now.          > proceed'partition create' successful.

Command Result : 0 (Success)

Next, the partition needs to be assigned to the client, i.e., your key server.

[] lunash:>client assignpartition -client -partition KeylessSSL

'client assignPartition' successful.

Command Result : 0 (Success)

After the partition has been assigned, run lunacm from your virtual server and initialize the partition.

vm$ lunacmLunaCM v7.1.0-379. Copyright (c) 2006-2017 SafeNet.
    Available HSMs:
    Slot Id ->              0    Label ->    Serial Number ->        XXXXXXXXXXXXX      Model ->                LunaSA 7.0.0      Firmware Version ->     7.0.1    Configuration ->        Luna User Partition With SO (PW) Signing With Cloning Mode    Slot Description ->     Net Token Slot

    Current Slot Id: 0
lunacm:>partition init -label KeylessSSL -domain cloudflare
  Enter password for Partition SO: ********
  Re-enter password for Partition SO: ********
  You are about to initialize the partition.  All contents of the partition will be destroyed.
  Are you sure you wish to continue?
  Type 'proceed' to continue, or 'quit' to quit now ->proceed
Command Result : No Error

2. Generate RSA and ECDSA key pairs and certificate signing requests (CSRs)

Before running the commands below, check with your information security and/or cryptography team to confirm the approved key creation procedures for your organization.

vm$ cmu generatekeypair -keyType=RSA -modulusBits=2048 -publicExponent=65537 -sign=1 -verify=1 -labelpublic=myrsakey -labelprivate=myrsakey -keygenmech=1Please enter password for token in slot 0 : ********
# cmu generatekeypair -keyType=ECDSA -curvetype=3 -sign=1 -verify=1 -labelpublic=myecdsakey -labelprivate=myecdsakeyPlease enter password for token in slot 0 : ********
# cmu listPlease enter password for token in slot 0 : ********handle=61   label=myecdsakeyhandle=60   label=myecdsakeyhandle=48   label=myrsakeyhandle=45   label=myrsakey

Using the keys created in the previous step, generate CSRs that can be sent to a publicly trusted Certificate Authority (CA) for signing.

# cmu requestCertificate -c="US" -o="Example, Inc." -cn="" -s="California" -l="San Francisco" -publichandle=45 -privatehandle=48 -outputfile="rsa.csr" -sha256withrsaPlease enter password for token in slot 0 : ********Using "CKM_SHA256_RSA_PKCS" Mechanism
# cmu requestCertificate -c="US" -o="Example, Inc." -cn="" -s="California" -l="San Francisco" -publichandle=60 -privatehandle=61 -outputfile="ecdsa.csr" -sha256withecdsaPlease enter password for token in slot 0 : ********Using "CKM_ECDSA_SHA256" Mechanism

3. Obtain and upload signed certificates from your Certificate Authority (CA)

Provide the CSRs created in the previous step to your organization’s preferred CA, demonstrate control of your domain as requested, and then download the signed SSL certificates. Follow the instructions provided in Uploading “Keyless” SSL Certificates.

4. Modify your gokeyless config file and restart the service

Lastly, we need to modify the configuration file that the key server will read on startup. Be sure to change the object=mykey and pin-value=username:password values to match the key label you provided and CU user you created.

Open /etc/keyless/gokeyless.yaml and immediately after:

private_key_stores:- dir: /etc/keyless/keys


- uri: pkcs11:token=KeylessSSL;object=myrsakey?module-path=/usr/safenet/lunaclient/lib/ uri: pkcs11:token=KeylessSSL;object=myecdsakey?module-path=/usr/safenet/lunaclient/lib/

With the config file saved, restart gokeyless and verify it started successfully.

$ sudo systemctl restart gokeyless.service$ sudo systemctl status gokeyless.service -l
