information, others receive this information can be encrypted by the public key corresponding to the private key. So they can be sure that this information is coming from you (at least you're encrypting it). This private key is equivalent to a "signature". (You add the secret, you sign the word) And this is the principle behind code signing in iOS. Code Signing ObjectsThe things that are related to code signing are: Provisioning Profiles,app Ids,udids ... In this section, we will explain one b
core data to draw a chart that describes the relationships between these objects. This is a developer-specific ( Development Profile ), the publisher's diagram will have a small difference. Private key: After Mac OS X, key is managed by an app called Keychain. You can find it in the application\utilities. Running keychain, you can see which public and private keys are in your name. Similar to this:
(1) Go to itunes to get Udid (for example: 3fd281cf67b)(2). Mobileprovision is just A (description) Proflie, this mobileprovision is generated based on the device's UUID of the phone. If mobileprovision doesn't contain your udid, your device won't be able to measure it. Then go to the iphone website, according to the certificate. CER regenerates the profile that joins its own UUID, then imports the CER and the new profile into the Xcode project build to select the new Proflie,Double-click the (a

Log on to the server and copy the public key of the ops user to the managed server. Replace the following IP addresses with your managed Server IP address.
