pkcs11helper Setup HSMs

Go PKCS#11 helper module for certificate signing using HSMs

Dependencies

OpenSSL

OpenSSL includes a conf file commonly found under Linux in /etc/ssl/openssl.cnf that is used to configure the HSM engines

On Ubuntu install the follwing packages:

OpenSSL

OpenSSL PKCS#11 engine

pkcs11-tool

Part of the OpenSC project.

Install on Ubuntu.

End Entity

The End Entity may be eg. a web server.

Create Private Key for End Entity

openssl genrsa -out localhost.key 2048

Generate CSR for End Entity Certificate

openssl req -sha512 -key ./localhost.key -new -out localhost512.csr.pem

HSMs

SoftHSM

SoftHSM is a software based HSM developed as part of the OpenDNSSec project.

Dependencies

On Ubuntu, install the following packages:

softhsm2

softhsm2-common

libsofthsm2

Configuration

SoftHSM2 Conf

On installation the default token can be seen, though may need to be run as root:

softhsm2-util --show-slots

Slot 0
Slot info:
Description:      SoftHSM slot ID 0x0                                             
Manufacturer ID:  SoftHSM project                 
Hardware version: 2.6
Firmware version: 2.6
Token present:    yes
Token info:
Manufacturer ID:  SoftHSM project                 
Model:            SoftHSM v2      
Hardware version: 2.6
Firmware version: 2.6
Serial number:                    
Initialized:      no
User PIN init.:   no
Label:

Initialise the token:

softhsm2-util --init-token --slot 0 --label "token0" --pin 1234 --so-pin 1234

A slot number will be generated:

The token has been initialized and is reassigned to slot 1601805484

show-slots will now provide the new slot's details:

softhsm2-util --show-slots

Available slots:
Slot 1601805484
Slot info:
Description:      SoftHSM slot ID 0x5f799cac

SafeNet DPoD

Configuration

SafeNet Configuration

Using a SafeNet DPoD account, download the installation files.

All of the following commands need a shell where the DPoD environment has been included using the source command:

cd /yoursafenetdpodpath
. ./setenv

If you are using an IDE then source this script in a terminal and then start the IDE from the terminal. The unit tests should then work with debug enabled within the IDE.
