Azure Dedicated HSM
Before you start
Make sure you have:
- Followed Microsoft's for deploying HSMs into an existing virtual network using Powershell
- Installed the
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 Azure Dedicated HSM device.
vm$ ssh tenantadmin@hsm [local_host] lunash:>hsm login Please enter the HSM Administrators' password: > ******** 'hsm login' successful. Command Result : 0 (Success) [local_host] 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.
[local_host] lunash:>client assignpartition -client azure-keyless -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 (64-bit) v7.2.0-220. Copyright (c) 2018 SafeNet. All rights reserved. Available HSMs: Slot Id -> 0 Label -> Serial Number -> XXXXXXXXXXXXX Model -> LunaSA 7.2.0 Firmware Version -> 7.0.3 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 a RSA key pair and certificate signing request (CSR)
Before running the commands below, check with your information security and/or cryptography team to confirm the approved key creation procedures for your organization.
# cmu generatekeypair -keyType=RSA -modulusBits=2048 -publicExponent=65537 -sign=1 -verify=1 -labelpublic=myrsakey -labelprivate=myrsakey -keygenmech=1 Please enter password for token in slot 0 : ******** # cmu list Please enter password for token in slot 0 : ********handle=51 label=myrsakeyhandle=48 label=myrsakey
Using the key created in the previous step, generate a CSR that can be sent to a publicly trusted Certificate Authority (CA) for signing.
# cmu requestCertificate -c="US" -o="Example, Inc." -cn="azure-dedicatedhsm.example.com" -s="California" -l="San Francisco" -publichandle=48 -privatehandle=51 -outputfile="rsa.csr" -sha256withrsa Please enter password for token in slot 0 : ********Using "CKM_SHA256_RSA_PKCS" Mechanism
3. Obtain and upload a signed certificate from your Certificate Authority (CA)
Provide the CSR 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 .
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
pin-value=username:password values to match the key label you provided and CU user you created.
/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/libCryptoki2_64.so&pin-value=password&max-sessions=1
With the config file saved, restart
gokeyless and verify it started successfully.
$ sudo systemctl restart gokeyless.service$ sudo systemctl status gokeyless.service -l
