I have an iOS app that is live in the app store, and I need to generate a new distribution certificate for signing the app. From what I understand, the app will always use the same private key, but needs a new certificate generated annually.
I am not using the same MacBook that I used to generate the original certificate, but I have the .p12 file that was exported from the original MacBook. I have imported it into the Keychain and have been successfully signing releases of my app.
Now I need to know how to generate a new certificate from my private key. I tried right clicking on my private key in the Keychain Access app and selecting "Request a Certificate From a Certificate Authority". Unfortunately this only resulted in the following cryptic message:
"The specified item could not be found in the keychain"
How can I generate a new distribution certificate for my app?
Find your p12 file and do the following
Generate the private key
openssl pkcs12 -in your.p12 -nodes -out private.key -nocerts
Generate the CSR
openssl req -new -key private.key -out request.csr
Then upload that to Apple
