local instructions for building push certificates

gistfile1.txt

Generating push certificates:

Go to iOS developer portal, go to "App IDs", open the production app ID and open
settings. Click "create certificate" and follow instructions to get
aps_production.cer and aps_development.cer. Make sure you use distinctive names
with date in the CSR so you can find the things later.

Import generated .cer files into keychain.

In keychain, select "my certificates" on the left, and expand the "apple
{development,production} IOS Push services" row that corresponds to the cert you
just made. Select the push services row *and* the row's child together, and
file->export them both as a single .p12 file.

run

openssl pkcs12 -in Certificates.p12 -out production_push_notifications_cert.pem
-nodes -clcerts

Done!
