Enigma Bridge Python Utilities for AWS

EnigmaBridge Amazon EC2 utils for PKI

This CLI setups a new fresh EJBCA (PKI) installation on EC2 instance with a new EnigmaBridge identity. EnigmaBridge is integrated with EJBCA as a new PKCS#11 crypto token, you can start using it to securely store your root CA keys.

The cli looks like the following:

--------------------------------------------------------------------------------
    Enigma Bridge AWS command line interface (v0.0.14)

    usage - shows simple command list
    init  - initializes the key management system

    More info: https://enigmabridge.com/amazonpki
--------------------------------------------------------------------------------
$>

Specific AMI is required - with JBoss EAP & EJBCA installed. More information on image setup can be found in IMG-INSTALL page.

For info on the network communication flow during the installation please refer to connections page.

Features

• EJBCA 6.3.1.1

• JBoss EAP 6.4

• SoftHSMv1-EnigmaBridge PKCS#11 adapter

• EnigmaBridge Dynamic DNS for AWS

SoftHSMv1-EnigmaBridge PKCS#11 adapter

SoftHSMv1-EB is a PKCS#11 interface for EnigmaBridge services. Using this adapter one can use our services using the generic PKCS#11 interface without need to modify the software.

Like in EJBCA case, there is no need to modify the software which supports PKCS#11, just plug our adapter to it and it starts working.

One can for example generate RSA keys via PKCS#11 adapter and call encrypt, decrypt, sign, verify operations on it. The keys are securely stored on EnigmaBridge servers, in the secure hardware. The cryptographic operation itself is performed in the secure hardware in a transparent way.

Dynamic DNS

Amazon provides IP address to your EC2 instance from the IP pool. This kind of address is re-allocated after your instance is turned off. After next start it will get a new IP address.

Usually its convenient to have a static IP so you can map it to the domain name or put in the config files, manuals, etc… You can buy Amazon Elastic IP which remains static even after instance restart or you can use our EnigmaBridge Dynamic DNS feature for the AWS.

During the initialization we allocate a new domains for your running instance, e.g., sunderland1.pki.enigmabridge.com. It has A record pointing to your current IP address.

After you restart your instance, our script is started. It connects to our DNS server and updates the A record for your domain in a secure way - request is signed with the key generated when domain was created.

Time to live of the record is 600 seconds so after the restart the hostname is updated in 10 minutes.

In this way you will get the static DNS name even if your IP changes.

Requirements

Generally the host need to have TCP port 443 open for LetsEncrypt domain verification. Without that you won’t get valid SSL certificate for your CA domain and you won’t be able to access administration console of your EJBCA installation in a secure way.

The EJBCA itself runs on TCP port 8443. It depends on you how you set it. It don’t necessarily have to be open to the world-fine. Its enough if you can access it somehow. e.g., it’s possible to access EJBCA admin via SSH tunnel. ssh -L 8443:localhost:8443 ami_ip

Init

The init command starts a new fresh installation. If a previous installation is present it asks user whether to proceed, backups the old installation databases and config files and installs a new one.

The installation process looks like this:

$> init
Going to install PKI system and enrol it to the Enigma Bridge FIPS140-2 encryption service.

We need your email address for:
   a) identity verification in case of a recovery / support
   b) LetsEncrypt certificate registration
It's optional but we highly recommend to enter a valid e-mail address (especially on a production system)

Please enter your email address [empty]: [e-mail]
Is this email correct? '[e-mail]' (Y/n):y

Checking if port 443 is open for LetsEncrypt, ip: 52.212.77.52

New domains registered for this host:
  - sunderland1.pki.enigmabridge.com
  - sr1.pki.enigmabridge.com

New configuration was written to: /etc/enigma/config.json

SoftHSMv1 configuration has been backed up to: None
New SoftHSMv1 configuration has been written to: /etc/softhsm.conf

SoftHSMv1 previous token database moved to: /var/lib/softhsm.old/softhsm_0018
SoftHSMv1 initialization: The token has been initialized.

Going to generate EnigmaBridge keys in the crypto token:
..................
EnigmaBridge tokens generated successfully
You can use these newly generated keys for your CA or generate another ones with:
  sudo -E -H -u jboss /opt/ejbca_ce_6_3_1_1/bin/pkcs11HSM.sh generate /usr/lib64/softhsm/libsofthsm.so 2048 signKey 0
  sudo -E -H -u jboss /opt/ejbca_ce_6_3_1_1/bin/pkcs11HSM.sh generate /usr/lib64/softhsm/libsofthsm.so 2048 defaultKey 0

Please setup your computer for secure connections to your PKI key management system:

Download p12 file: /home/ec2-user/ejbca-admin.p12
  scp -i <your_Amazon_PEM_key> [e-mail]:/home/ec2-user/ejbca-admin.p12 .
  Key import password is: g5Bkg79Lvk3Q8jVC

The following page can guide you through p12 import: https://enigmabridge.com/support/aws13076
Once you import the p12 file to your computer browser/keychain you can connect to the PKI admin interface:

  https://sr1.pki.enigmabridge.com:8443/ejbca/adminweb/

Troubleshooting

Error in installation of dependencies (cryptography, pyOpenSSL): sorry, but this version only supports 100 named groups [100-named-groups]

Solution: Install downgraded version of pycparser and pyOpenSSL:

pip install pycparser==2.13
pip install pyOpenSSL==0.13
pip install cryptography

You may need to install some deps for the python packages

yum install gcc g++ openssl-devel libffi-devel dialog

SNI on Python < 2.7.9

TLS SNI support was added to Python. For earlier versions SNI needs to be added to Requests networking library.

pip install urllib3
pip install pyopenssl
pip install ndg-httpsclient
pip install pyasn1

Mac OSX installation

For new OSX versions (El Capitan and above) the default system python installation cannot be modified with standard means. There are some workarounds, but one can also use --user switch for pip.

pip install --user cryptography
