Overview

This directory contains configuration files and notes on how to set up the DataONE Certificate Authority using OpenSSL as the CA application. OpenSSL generates all files needed for the CA, including certificate requests, keys, certificates, and certificate revocation lists.

The DataONE Certificate Authority is governed by a Root CA, which delegates all certificate signing and management to a Production CA. The private key for the Root CA is offline and completely protected, which protects the CA should somehow the Production CA private key be compromised. This document shows the steps used to create both the Root CA and the Production CA, as well as to perform common options such as creation and revocation of certificates with the Production CA. The operations have been encapsulated in the ca shell script.

There is also a Test CA, used for generating certificates for servers in the dev, staging, and sandbox environments, but this CA is completely independent of the Production CA and its certificates will not be accepted in the production environments. The Test CA has the same hierarchy as the Production CA, with a Root CA delegating certificate signing and management to an intermediate CA.

Key Security

New certificates created using the CA have two components: the certificate and the private key:

The certificate can be publicly exposed, and should be added to GitHub and checked in.
Keys MUST be kept private. After the certificate and private key are provided to the Node administrator (see publish_cert_orcid in the "Use" section, below), any local copies of the private key should be deleted. (We no longer keep copies of these Node keys, since a new cert and key can be generated easily if a key is lost or compromised.)

The private keys needed to issue certs are contained in a binary sparsebundle file. Contact DataONE root system administrators for access.

VERY IMPORTANT! Since merge commits are not possible with a binary file, ALWAYS...

Pull the latest version of the sparsebundle before starting any changes.

Inform other certificate admins on slack that you are working in the bundle.

Push your sparsebundle changes immediately, and inform the other admins when you're done.

Requirements

The CA scripts rely on the BASH shell and are developed on OS X (bash 3.2.53) though should work without modification on Linux. Dependencies are:

OpenSSL
Standard command line tools such as sed, awk, cut, sort, git

Installation

Installing the DataONE CA involves the following steps. In these instructions, it is assumed that the CA software is being installed in ${HOME}/Projects/DataONE/tools, identified by ${CA_HOME} in the examples. Adjust as appropriate for your system.

The CA is distributed from GitHub. Checkout the tool to the desired location

  cd ${HOME}/Projects/DataONE/tools
  git clone git@github.com:DataONEorg/ca.git
  export CA_HOME="$(pwd)/ca"

Create a symbolic link for /var/ca to the checkout location:
```
  sudo ln -s ${CA_HOME}/ca /var/ca
```
Mount the encrypted volume using Finder or the command line when ready to create certificates or update the revocation list:
```
  hdiutil attach -agentpass /path/to/encrypted/DMG
```

Note -- Do not keep the encrypted volume with the keys on your laptop or any other device that is regularly connected to the Internet. Keep it on a USB stick or some other physical media that can be disconnected.

Verify the installation by running the cert_status script:

  cd ${CA_HOME}
  ./cert_status

If all is good, then the script will examine the contents of the Test Environment certificates folder and report on the status of each .pem file found there. The output is lengthy, and looks something like:

  {"what":"Certificate Status",
   "Generated":"2015-03-18T11:23:26.000+00:00",
   "content":[
  {
   "File_name"   : "/Users/vieglais/Projects/DataONE_61385/svn/software/tools/trunk/ca/DataONETestIntCA/certs/cn-dev-orc-1.pem",
   "Author"      : "",
   "Serial"      : "DA3263A2A12D004B",
   "DN"          : "DC=org,DC=dataone,DC=test,CN=cn-dev-orc-1",
   "Created"     : "2012-07-24T03:39:45.000+00:00",
   "Expires"     : "2015-07-24T03:39:45.000+00:00",
   "Expires_days": 127,
   "Revocation"  : "Revoked",
   "Validity"    : "Valid"
  }
  ,
  {
   "File_name"   : "/Users/vieglais/Projects/DataONE_61385/svn/software/tools/trunk/ca/DataONETestIntCA/certs/cn-dev-orc-1.test.dataone.org-1.pem",
   "Author"      : "",
   "Serial"      : "DA3263A2A12D0055",
   "DN"          : "DC=org,DC=dataone,CN=cn-dev-orc-1.test.dataone.org",
   "Created"     : "2012-07-27T21:25:34.000+00:00",
   "Expires"     : "2015-07-27T21:25:34.000+00:00",
   "Expires_days": 131,
   "Revocation"  : "Revoked",
   "Validity"    : "Valid"
  }
  ...

and so on.

Use

Four shell scripts are included to assist with certificate management:

ca: This is the main script for creating and revoking certificates.

cert_status: This script reports the status for a single certificate or all certificates in an environment.

publish_cert and publish_cert_orcid: Provide a convenient mechanism for packaging a certificate and key, and placing them in a secure location for download by an authenticated user.

The publish_crl script (for publishing the certificate revocation list to the CRL servers) has been move to the SHA-1_ARCHIVE directory. In practice no clients rely on the CRL -- see this blog post for more explanation. If you still need details of how to use the publish_crl script, see the original README file

`ca`

The shell program ca can be used to manage certificates from both the Test CA and the Production CA. It determines which CA to use based on commandline arguments. Type ./ca -h to see the usage help for the ca utility.

To install the DataONE certificate authority, simply:

install openssl on your machine
Check out a working copy of the CA from the DataONE GitHub repository
Mount the private key encrypted volume under /Volumes/DataONE

The ca utility can create, revoke, and display certificates, and can generate the Certificate Revocation List (CRL) for either of the CAs. Examples follow:

To create a Production certificate for the MN with nodeid "KNB":

  ./ca -c Prod urn:node:KNB

To display a Production certificate for the MN with nodeid "KNB":

  ./ca -d Prod urn:node:KNB

To revoke a Production certificate for the MN with nodeid "KNB":

  ./ca -r Prod urn:node:KNB

To generate a CRL for the Prod CA:

  ./ca -g Prod

Any of these commands can be made to work on the Test CA instead by switching Prod to Test.

Once new CSRs, Certificates, and CRLs have been generated, they should be added to GitHub and all modified files should be checked in to GitHub so that others managing the CA can access all the updated content. The only exception are the private keys that are generated, which should be given to the MN operator along with instructions on how to protect the private key. The private key should be deleted from the CA to avoid possible exposure of the keys.

`cert_status`

The script cert_status provides a mechanism to report on the status of a single certificate or all certificates within the Production or Test environments. Report output is in JSON or pipe (|) separated values and includes the attributes:

File_name: Full path to the certificate
Author: The name of the GitHub user that checked in the certificate
Serial: The certificate serial number
DN: The certificate Distinguished Name
Created: Indicates when the certificate was created
Expires: Indicates when the certificate will expire
Expires_days: Number of days until the expiration date
Revocation: Indicates if the certificate appears in the revocation list
Validity: Indicates if the test openssl verify passes.

cert_status can also be used to generate VCalendar .ics files, one for Production and one for the Test environment, that includes dates for certificate and revocation list expiry. These are checked in to GitHub and can be subscribed to using Google Calendar or iCal using the calendar locations of:

https://raw.githubusercontent.com/DataONEorg/ca/main/Prod_events.ics

for the Production environment, and:

https://raw.githubusercontent.com/DataONEorg/ca/main/Test_events.ics

for the Test environment.

Example Show status of a single certificate in test environment:

  ./ca cert_status -A DataONETestIntCA/certs/urn\:node\:mnTestGulfWatch.pem

Example Show status of a single certificate in production environment, using the default locations for certificates and CRL:

  ./cert_status -A -P DataONEProdIntCA/certs/urn\:node\:GULFWATCH.pem

Example Show status of a single certificate in production environment, explicitly indicating which certificates and CRL to use:

  ./cert_status -A \
    -a DataONEProdIntCA/certs/DataONEProdIntCA.pem \
    -c DataONEProdRootCA/certs/DataONEProdRootCA.pem \
    DataONEProdIntCA/certs/urn\:node\:GULFWATCH.pem

Example Generate a pipe delimited text file reporting on all the test certificates:

  ./cert_status -S > testcerts.csv; \
  for f in $(find DataONETestIntCA/certs -name *.pem); \
    do ./cert_status -A -s $f >> testcerts.csv; done

or:

   ./cert_status -s -A DataONETestIntCA/certs

Example Generate a pipe delimited text file reporting on all the production certificates:

  ./cert_status -H > testcerts.csv; \
  for f in $(find DataONETestIntCA/certs -name *.pem); \
  do ./cert_status -A -s \
   -a DataONEProdIntCA/certs/DataONEProdIntCA.pem \
   -c DataONEProdRootCA/certs/DataONEProdRootCA.pem \
  $f >> prodcerts.csv; done

or:

  ./ca cert_status -s -A -P DataONEProdIntCA/certs

Example Generate a calendar of events in .ics format for production environment certificate expirations and the next update time for the CRL. Output is to the file "Prod_events.ics" for the production environment or "Test_events.ics" for the test environment. The calendar can be subscribed to using the respective GitHub URL:

  ./ca cert_status -P -L

`publish_cert` and `publish_cert_orcid`

The scripts publish_cert and publish_cert_orcid each provide a convenient mechanism to package a certificate, its key, and the CSR used to generate the certificate into a .zip file and upload it to the distribution server (currently https://project.dataone.org/).

The script accepts two arguments:

the ID of the user who will retrieve the package. this will be:
- the user's LDAP uid, when using publish_cert, or
- the user's ORCID, when using publish_cert_orcid (but only the numerical part; see below).
the path to the certificate. The certificate is expected to be located in the certs folder of the respective CA.

Note -- The resulting file names have the ":" character replaced with "_".

The script uses ssh to connect to the distribution host, create a target folder if necessary, and upload the package .zip file. As such, it is necessary for the user running the script to have SSH access to the distribution host and write access to the destination folder (/var/www/users).

Example Share a certificate and key for user vieglais:

  # For LDAP:
  ./ca publish_cert vieglais DataONETestIntCA/certs/urn:node:ATestCert.pem
  
  # or for ORCID:
  ./ca publish_cert 0000-0002-6513-4996 DataONETestIntCA/certs/urn:node:ATestCert.pem

Note -- Only the numerical part of the ORCID should be used, as shown in the example above!

The resulting package would be downloadable from:

https://project.dataone.org/~vieglais/urn_node_ATestCert.zip

After unzipping, the result would be:

  urn_node_ATestCert/
    info.txt
    urn_node_ATestCert.pem
    urn_node_ATestCert.csr
    private/
      urn_node_ATestCert.key

The file info.txt contains general information about the certificate generated by the cert_status program.

Appendix 1: Additional notes on OpenSSL setup and usage

OpenSSL was used to create the various CA files and operate the CA. The following sections are a synopsis of how all the CAs were created and how various CA functions can be run using OpenSSL alone. The ca shell script automates some of these functions (most notably for Node certificate creation), so their inclusion here is mainly as a reference and not intended for typical usage.

For more information on OpenSSL, see openssl.org. For more detail on the configuration files (openssl.cnf or openssl.tmpl), see the openssl documentation or this Openssl.conf walkthrough

SHA-256 Updates, Cross-Signing, and Naming Scheme

The original CA certificates were generated using SHA-1, which is now considered insecure. In 2024, therefore, new SHA-256-encrypted Root CAs were generated, and these were used to "cross-sign" the intermediate certs. This process entailed generating new Intermediate CA certs for Production and Test, while ensuring:

they had the same Subject/DN as the old intermediate certs, and
they were signed with the original private keys that were used to sign the old intermediate certs.

See Appendix 2 for a brief overview of how Cross Signing works

At the same time, all the old SHA-1 contents of this repo were moved into the SHA-1_ARCHIVE subdirectory (see Appendix 3). A new, clearer and more-consistent naming convention was then adopted for the new directories and files, as follows:

                          PRODUCTION                         TEST
-----------------------------------------------------------------------------------
### ROOT ###
directory name:         DataONEProdRootCA             DataONETestRootCA
     cert name:         DataONEProdRootCA.pem         DataONETestRootCA.pem
           CN =        "DataONE Prod Root CA"        "DataONE Test Root CA"

### INTERMEDIATE ###
directory name:         DataONEProdIntCA              DataONETestIntCA
     cert name:         DataONEProdIntCA.pem          DataONETestIntCA.pem
(see Note) CN =        "DataONE Production CA"       "DataONE Test Intermediate CA"

NOTE: The Intermediate CNs are inconsistent because the Subjects (and therefore the CN values) for the Intermediate certs must match those in the old SHA-1 root CAs, in order for cross-signing to work.

If we have the opportunity to change the Intermediate CNs in the future, we can make them consistent by renaming "DataONE Production CA" to "DataONE Prod Intermediate CA".

NOTE - in addition to the DataONE Root and Intermediate CA certs, the Prod and Test CA chain files currently (Jan 2024) also include the following 3 CILogon CA certs, for legacy reasons. (these were copied across from the old SHA-1 cert chains):

    subject=DC = org, DC = cilogon, C = US, O = CILogon, CN = CILogon Basic CA 1
    issuer=DC = org, DC = cilogon, C = US, O = CILogon, CN = CILogon Basic CA 1

Appendix 2: Certificate Cross-Signing

When we started issuing DataONE node certificates in 2012, we were using SHA-1-encrypted Root and Intermediate CA certs. Since then, SHA-1 has widely been recognized as insecure, and has been replaced with SHA-256. However, since it would be a huge task to re-issue all the node certificates currently in use, we need a way of upgrading our CA certs to SHA-256, whilst keeping them backwards-compatible with existing node certs. This can be done by a process known as Cross Signing. (For an excellent overview of how cross signing works, see Scott Helme's blog).

Basically, here's what happens when a DataONE Node cert (or any cert, for that matter) is created:

the subscriber's information (name, domain name, etc...) is used to fill out a "pre-certificate".
The pre-cert is then run through a hash function (SHA-256 in this case), to obtain its digest.
That digest is then encrypted with the DataONE private key (the one that was used to create the Intermediate CA cert).
This encrypted digest is the "signature", and once it is appended to the end of the pre-cert, we now have a signed certificate that can be issued to the Subscriber.

(It's interesting to note that this process does not require a root CA cert or an Intermediate CA cert; only the Intermediate's private key is needed).

Later, when a DataONE Node cert is validated against the DataONE Intermediate CA cert (from the cert chain on the server), 2 things are checked:

the signature on the bottom of the Node cert is decrypted using the Intermediate CA's public key. This tells us that if the CA's public key can decrypt it, the CA's private key must have encrypted it, so authenticity has been verified.
the server then calculates its own hash of the Pre-Certificate to compare to the hash stored in the signature and determine if they are identical. If they match, the certificate has not been tampered with, so Integrity has been verified.

Now we know we can trust the contents of the Node cert, authentication can be completed by simply verifying that the "Issuer" field in the Node cert matches the "Subject" field in the Intermediate cert.

So - in summary - only 2 pieces of information from the Intermediate certificate are used to authenticate the Node cert:

the public key (used to decrypt the signature), and
the Subject (used to verify the Issuer)

Therefore, it is possible to have two (or multiple) different versions of the Intermediate cert, provided they each contain the same public key and the same Subject!

This is why cross signing is possible.

So - all we need to do, in order to create a cross-signed SHA-256 Intermediate is:

Create a new SHA-256 self-signed Root CA cert
For the Intermediate cert, first create a certificate signing request (CSR), ensuring 2 things:
1. The "Subject" exactly matches the one in the old SHA-1 Intermediate cert.
2. The CSR is signed by the ORIGINAL private key that was used to sign the old SHA-1 Intermediate CSR.
  - (The public key that will be included in the final cert is generated from this private key, so if we use the same private key, the new public key in the new Intermediate cert should match the old public key in the old Intermediate cert)
Now create the new Intermediate cert from this CSR, signing it with the new Root CA Private Key from step (1) above.

Now we can replace the old sha-1 CA cert chain with this new SHA-256-based CA chain, and it will work with all the existing Node certificates and any new Node certs issued against the new CA.

(Final note; "Cross signing" is a misnomer. it implies that one intermediate certificate is signed by two different Root CAs. This is not the case, as can be seen above.)
