Code Signing Identity and Provisioning Profiles – What Are the Differences?
Distinction- iOS Code Signing Identity & Provisioning Profiles
What is Code Signing Identity?
The term Signing allows iOS to recognize who has signed the application while verifying that it hasn’t been tampered since its signing. And, the Signing Identity in the Code Signing Identity is something, which consists of a public and private key pair that are specially created by an Apple.
In other words, Code Signing Identity is referred to the Common Name of the certificates which are installed in the Developer’s machine Keychain. In Xcode an integrated development environment (IDE), it appears as an option in the build setting as a list option from which developers can select the Identity to be used for CodeSign. Likewise, it contains a lot of information which are encoded in every section of the menu.
To be more precise, if you open Keychain Access and double click “iPhone Development” or “iPhone Distribution” you will see the certificates which show the information which is encoded into the certificates issued to developers by Apple.
What is a Provisioning Profile?
- Which code can be run?
- Who can run the given code?
- On which devices the code can be run?
Certificates authorize which users can build or distribute the application.
Device ID is a list of devices UDIDs, which are authorized for running the application.
In other words, Provisioning Profile is a container of all the component needed by an operating system for deciding whether to let an application run on it or not. Provisioning Profile is used for enabling application debugging on development devices, ad-hoc, and enterprise distribution. It’s not a property list, but a file encoded in the CMS (Cryptographic Message Syntax). Likewise, CMS format is used for encoding a provisioning profile, because it helps in allowing the profile to be signed, so it cannot be changed after the issuance.
