PKCS12_parse: unsupported error with Ruby 3.2

[alexdunae]

Ruby 3.2 includes OpenSSL 3. This causes issues signed Passbook passes using a p12 archive.

The fix is to extract the certificate and private key from your p12 file and pass those individually to the Passbook gem.

Passbook.configure do |passbook|
  passbook.wwdc_cert = Rails.root.join('config/apple/wwdr.pem')


  # no longer works in Ruby 3.2 / OpenSSL 3
  # passbook.p12_certificate = Rails.root.join('config/apple/whatever.p12')
  # passbook.p12_password = ''

  # this works in Ruby 3.2
  passbook.p12_certificate = Rails.root.join('config/apple/whatever.crt')
  passbook.p12_key = Rails.root.join('config/apple/whatever.key')
end
