Use of the iOS Development Certificate and configuration file, and the ios certificate configuration file
Prerequisites

As we all know, to develop iOS applications, you must have an iOS certificate and Provisioning Profiles:

1. What is an iOS certificate and how is it associated with an app?
2. What is the difference between iOS development certificate and production certificate? How can I use it?
3. What is the relationship between certificates and Provisioning Profiles? How can I use the configuration file in Xcode?
4. How can I apply for a certificate and configuration file?
5. What is Key Pair (Public Key/private Key )? How is the certificate associated?
6. What is the role of signature?

Preparations

If you want iOS development, you must first meet the following conditions:
1. First, you must have an Apple Developer Account)

  • Only a developer account can apply for a development/release certificate and corresponding configuration file.
  • Developer accounts are divided into two types: Individual (personal or Company developer account $99) and Company/Organization (Enterprise developer account $299.

2. to debug a real machine, you must have at least one Mac development machine (iMac or MacBook) with Mac OS X/Xcode installed)

1. log on to the iOS Dev Center

If you already have an apple developer account, log on directly.Apple Developer CenterApply for a development certificate.

  • Logon page

  • Select "Certificates, Identifiers & Profiles". The following page is displayed. any item in the iOS Apps column is selected.

The four items are described below.

2. Certificates (certificate), Identifiers (identifier), Devices (device), Provisioning Profiles (supply configuration files)

In order to facilitate understanding, we disrupt the order and introduce these four items respectively.

2.1. Identifiers

Identifiers are Identifiers, which are equivalent to ID cards. They are used to create the following three IDs:
App IDs
Pass Type IDs
Website Push IDs

2.1.1. About App IDs

The App ID is the unique identifier of the application:

  • The App ID and Bundle Identifier in Xcode are consistent (Explicit) or matched (Wildcard.

FEDE676C-1DFC-4958-B52E-3B2DF73A35B3.png
  • The App ID string generally uses Company Identifier (Company ID) in the reverse-domain-name format as the Prefix (Prefix/Seed) and generally contains no more than 255 ASCII characters.
  • You can Register (Register) or Delete (Delete) registered App IDs on the Developer MemberCenter website.
2.1.2. Create an App ID
  • Select "App IDs" in the "Identifiers" column to view all applied App IDs and click "+" in the upper right corner"

  • Go to the Register iOS App ID page and enter the Name in the "Name" Field of "App ID Description ".

    72E71207-FB31-4BC6-8E03-7EDADE9A82EC.png
  • Enter the App ID (Anti-Domain Name format, such as com. company. test) in the Bundle ID field in the "Explicit App ID" column)
    • Here, "Bundle ID" corresponds to "Bundle identifier" in Xcode"
    • Explicit App ID: Unique App ID, used to uniquely identify an application. For example, the App ID "com. apple. garageband" is used to identify the App whose Bundle Identifier is "com. apple. garageband.
    • Wildcard App ID: the App ID that contains wildcards to identify a group of applications. For example,"(Actually Application Identifier Prefix) indicates all applications; while" com. apple.It can indicate all applications of Bundle Identifier starting with "com. apple.

  • Click "Edit" to Edit the App ID.
2.2. Certificates2.2.1. description

The iOS certificate is a digital certificate used to prove the legitimacy and integrity of the iOS App content (executable code. For applications (Apps) that want to be installed on a real machine or published to an AppStore, only Signature Validated can ensure that the source is trusted, it also ensures that the App content is complete and not tampered.

  • A digital certificate is a file digitally signed by the certificate authorization center that contains information about the public key owner and the public key. It is time-sensitive and valid only for a specific period of time.
  • There are two types of iOS certificates:Development Certificate)AndProduction certificate).
2.2.2. Generate the certificate request file (CSR) 

You can request a certificate from the certificate authority through the Keychain certificate assistant. When adding a certificate (Certificates) to the iOS Dev Center, you need to upload and modify the CSR file.

  • Open the Keychain and click "access key"-> "Certificate assistant"-> "request certificate from the Certificate Authority" in the menu bar"

  • Enter the Development Account email and common name, and select "store to disk ".

  • After you continue and select the storage location, the Keychain will generate a CSR (Certificate Signing Request) file containing the developer's identity information. In addition, a Pair of Public/Private Key Pair is added to the Keychain Access-> Keys (Key.
