Signed Searchset Bundle Example

The following page content is DRAFT and open for review

This is a Jupyter Notebook which uses openSSL, Python 3.7, and the Python jcs and jose libraries to create a JSON Web Signature (JWS)(see RFC 7515), attach it to a FHIR Bundle and validate it. Its source code be found here

Although self-signed certificates are used for the purpose of these examples, they are not recommended for production systems.

Sender/Signer Steps

1. Generate RSA256 public and private keys for signing the bundle

DO THIS STEP ONLY ONCE

2. Create a sef-signed certificate for authenticating the signer

create the public and private keys and cert using openssl on the command line.

  1. pre-configure the self-signed cert with a configuration file
[req]
default_bit = 4096
distinguished_name = req_distinguished_name
prompt = no
x509_extensions = v3_ca

[req_distinguished_name]
countryName             = US
stateOrProvinceName     = California
localityName            = Sausalito
organizationName        = HealtheData1
commonName              = Eric Haas, DVM
emailAddress            = ehaas@healthedata1.org

[v3_ca]
basicConstraints = CA:TRUE
keyUsage=nonRepudiation, digitalSignature, keyEncipherment
subjectAltName = @alt_names

[alt_names]
DNS.1 = www.healthedatainc.com

2. generate the public and private keys and cert

!openssl genrsa -out private-key.pem 3072
!openssl rsa -in private-key.pem -pubout -out public-key.pem
!openssl req -new -x509 -key private-key.pem -outform DER -out cert.der -days 360 -config cert.config

For the purpose of this example display the keys (normally would never share the private key)

!cat private-key.pem
!echo
!cat public-key.pem

3.2. Prepare Payload

The payload is the base64_url form of the canonicalized version of the searchset Bundle before attaching the signature

Canonicalize the bundle using IETF JSON Canonicalization Scheme (JCS) before adding the signature element:

  • Remove the id and meta elements if present before canonicalization
  • The base64_url of the payload entry is combined with 3.3 below using the jws.sign method.
from jcs import canonicalize #package for a JCS (RFC 8785) compliant canonicalizer.

Receiver/Verifier Steps

1. Remove the Bundle.signature element from the Search Bundle resource

  • For this example using the python dictionary object from above, but in real life, Therefore it would need to be stored unaltered in order to perform these next steps.
try:
  recd_signature = searchset_bundle.pop("signature")
except:
  pass

2. Canonicalize the bundle using IETF JSON Canonicalization Scheme (JCS):

  • Remove the id and meta elements if present before canonicalization
searchset_bundle_id = searchset_bundle.pop("id") # remove id
searchset_bundle_meta = searchset_bundle.pop("meta") # remove meta
canonical_bundle = canonicalize(searchset_bundle)
canonical_bundle

3. Transform canonicalize Bundle to a base64 format using the Base64-URL algorithm.

from base64 import urlsafe_b64encode
recd_b64_canonical_bundle  = urlsafe_b64encode(canonical_bundle).decode()
recd_b64_canonical_bundle = recd_b64_canonical_bundle.replace("=","") #remove end padding to normalize
