Faraday client certificate authentication

faraday_cert_auth.rb

# I'm starting with a .pfx, so the first step is to get it to a .pem caintaining the cert and key
# This can be done using the following command
#
#    openssl pkcs12 -in certs/mycert.pfx -out certs/mycert.pem -nodes
#
 
require 'faraday'
require 'openssl'
 
# create an x509 certificate
def cert_object
  OpenSSL::X509::Certificate.new File.read('certs/mycert.pem')
end
 
# create PKey
def key_object
  OpenSSL::PKey.read File.read('certs/mycert.pem')
end
 
# build the connection object
connection = Faraday::Connection.new 'https://my.secure.site.dev', ssl: {
  client_cert: get_cert,
  client_key: get_key,
  verify: false
}
 
connection.post do |req|
  req.url '/secure-endpoint'
  req.body = "secret data"
