Create .p12 file from an iPhone Developer Certificate on Windows

Follow along as I show you how to create a P12 file from your iPhone Developer Certificate using OpenSSL on a Windows machine. Visit http://www.tutorialsbyibrent.com for more information.

Follow me on Twitter: @iBrent

Here is the text for creating the PEM:

openssl x509 -in developer_identity.cer -inform DER -out developer_identity.pem -outform PEM

and for creating the .p12 file:

openssl pkcs12 -export -inkey mykey.key -in developer_identity.pem -out iphone_dev.p12

so much easier to create a .p12 file by going into CS5 Flash and choosing Adobie Air,

then just go to the Air settings and signature tab, leave everything blank and choose create, put in your details and it will save as a .p12 file. all done.

@huttd You realize that the .p12 generated by Flash isn't the same as the one I show in this tutorial, right? The .p12 Flash generates won't let you sign the app for testing or deployment on an iOS device.

For anyone who got a "unable to write a random state" with, I ran the cmd prompt as an admin, and it worked fine. In the start menu, just type 'cmd' in the search field, and right click 'cmd' and click 'Run as administrator"

"No certificate matches private key"... :(( .. any idea why?

@DrN0OB To be honest it's easier to do this on a Mac, so be sure to check out my tutorials showing how to do that. In general for a distribution key, you need to create a provisioning profile in the distribution tab on your iOS dev account. I've got videos on that as well. Otherwise, if you know you've done all that, make sure you have the correct app id in your -app.xml that matches the Distribution cert, etc. Good luck!

I keep getting an error "No Certificate Matches Private Key" when I change everything to "distribution_identity"

[DrN0OB]

is there a way to do this with a distribution key?

[huttd]

[domintor3]

after i type what you have at 1:54 i get the following error: 'openssl' is not recognized as an internal or external command.

Any suggestions?

[redpedak]

what should i type when it says 'enter export pass: because i keep typing a same word for verefiying and export : and tells me unable to write a random state

[ddskier]
