cert

Twitter: @FastlaneTools License Gem

Automatically create and maintain iOS code signing certificates.

cert is focused exclusively on code signing. You can create new code signing identities for different environments (development and distribution) and use any existing valid certificates installed locally.

cert is part of fastlane: The easiest way to automate beta deployments and releases for your iOS and Android apps.

Installation

Note: It is recommended to use match according to the codesigning.guide for generating and maintaining your certificates. Use cert directly only if you want full control over what's going on and know more about codesigning.

sudo gem install cert

Make sure, you have the latest version of the Xcode command line tools installed:

xcode-select --install

Why?

Please check out this guide which shows how to manually create an iOS code signing profile and a provisioning profile using the Apple Developer Portal.

After checking out the guide, take a look how cert and sigh do all that for you.

In the gif I used cert && sigh, which will first create an iOS code signing certificate and then a provisioning profile for your app if cert succeeded.

Usage

cert

This will check if any of the available signing certificates is installed on your local machine.

Only if a new certificate needs to be created, cert will

  • Create a new private key
  • Create a new signing request
  • Generate, downloads and installs the certificate
  • Import all the generated files into your Keychain

cert will never revoke your existing certificates. If you can't create any more certificates, cert will raise an exception, which means, you have to revoke one of the existing certificates to make room for a new one.

You can pass your Apple ID:

cert -u [email protected]

For a list of available commands run

cert --help

Keep in mind, there is no way for cert to download existing certificates + private keys from the Apple Developer Portal, as the private key never leaves your computer.

Environment Variables

Run cert --help to get a list of all available environment variables.

Use with sigh

cert becomes really interesting when used in fastlane in combination with sigh.

Update your Fastfile to contain the following code:

lane :beta do
  cert
  sigh(force: true)
end

force: true will make sure to re-generate the provisioning profile on each run. This will result in sigh always using the correct signing certificate, which is installed on the local machine.

How is my password stored?

cert uses the password manager from fastlane. Take a look the CredentialsManager README for more information.
