Certificate (.p12) File

[NathanDaniels]

How do I convert an iOS distribution certificate (.cert) to a .p12 file using Windows only? Is this even possible? A Google search indicated that it might be possible using openSSL, however I haven't yet got that method to work. Are you able to point me to any instructions/documentation on how to get the .p12 file using Windows only? Thanks.

A .p12 file contains both your iOS Distribution Certificate (.cer) and your private key. They must match. On a Mac this is achieved by importing your .cer into Keychain Access and making sure that your private key is attached to the iOS Distribution Certificate prior to exporting it as a .p12 file.

On Windows, I don't know of a way to do this step, sorry.

However, after you got your .p12 file, you no longer need access a Mac since you can make use of Cloud Make.

Hi Nathan,

The answer is yes. 

If you want to create a p12 file using openSSL on a windows machine, you need to create the CSR file and the Private key using openSSL (I did this on a windows machine, but I guess you don't have to). then you can create a iOS certificate using the CSR on the Apple Developer website.

As Stephen mentioned, once you have the certificate and the corresponding private key, you can create p12 file using openSSL.
