You must obtain a Website Push certificate from apple which requires a iOS developer license or a Mac developer license

Starting February 2016, you will also need a copy of the Apple intermediate cert (WWDR Certificate, expiring 02/07/23)

require 'push_package'

website_params = {
  websiteName: "Bay Airlines",
  websitePushID: "",
  allowedDomains: [""],
  urlFormatString: "",
  authenticationToken: "19f8d7a6e9fb8a7f6d9330dabe",
  webServiceURL: ""

iconset_path = 'path/to/iconset'
certificate = 'path/to/certificate.p12' # or certificate_string
intermediate_cert = 'path/to/AppleWWDRCA.cer'
package =, iconset_path, certificate, 'optional cert password', intermediate_cert)'path/to/save')
$> push_package --website-json=./website.json --iconset-path=/path/to/project/iconset --output-dir=./ --certificate=./Certificate.p12

# verify the localhost.crt

# verify the localhost.key

# print information about the certificate to STDOUT
openssl x509 -in spec/fixtures/localhost.crt -text -noout

# generate a new rsa key

# generate a new csr from using an existing key
openssl req -new -sha256 -key spec/fixtures/localhost.key -out spec/fixtures/localhost.csr

# generate a new certificate using an existing csr and private key
openssl x509 -req -days 3650 -in spec/fixtures/localhost.csr -signkey spec/fixtures/localhost.key -out spec/fixtures/localhost.crt

# export the certificate as a p12
# make sure to set the passphrase to 'testing' because the specs depend on it
