  • Generates manifest.json
  • Signs package with required signature
  • Creates pushPackage.zip


gem install push_package


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: "web.com.example.domain",
  allowedDomains: ["http://domain.example.com"],
  urlFormatString: "http://domain.example.com/%@/?flight=%@",
  authenticationToken: "19f8d7a6e9fb8a7f6d9330dabe",
  webServiceURL: "https://example.com/push"

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

Development/Test Certificates

# verify the localhost.crt
openssl verify spec/fixtures/localhost.crt

# verify the localhost.csr
openssl req -text -noout -verify -in spec/fixtures/localhost.csr

# verify the localhost.key
openssl rsa -in spec/fixtures/localhost.key -check -noout

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

# generate a new rsa key
openssl genrsa -out spec/fixtures/localhost.key 2048

# 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
openssl pkcs12 -export -out spec/fixtures/self-signed.p12 -inkey spec/fixtures/localhost.key -in spec/fixtures/localhost.crt
