CODE SIGNING
SLIDE 17
SIGNING
App Provisioning Profile Certificate Private Key
Code Signing
hash Signature App
Signed App
Public Key
SLIDE 18
VERIFICATION
App hash Signature Public Key Decrypted hash
Decrypt
= Valid App
SLIDE 19
CODE SIGNING
Ensures identity of developer of an application Ensures integrity of application content (has not been manipulated after submission to App Store)
SLIDE 20
CODE SIGNING
Developer signs with developer profile when submitting to App Store Apple resigns application with their own certificate before distributing to users Apple’s certificate doesn’t expire!
SLIDE 21
CODE SIGNING
Certificate: Public Key + Identifying information Provisioning Profile: Combination of entitlements, certificate and list of viable devices
SLIDE 22
CERTIFICATE
SLIDE 23
ENTITLEMENTS.PLIST
SLIDE 24
ENTITLEMENTS.PLIST / CAPABILITIES
SLIDE 25
ENTITLEMENTS / CAPABILITIES
Defines which privileges an app has (e.g. access to iCloud) App’s privileges need to match the ones in corresponding provisioning profile
SLIDE 26
CODE SIGNING SUMMARY
Entitlements define what app is allowed to do Entitlements need to be specified in Provisioning Profile Provisioning Profiles specifies with which Certificates an app can be signed Code signing ensures that app developer can be identified and that app content isn’t modified after signing
SLIDE 27
INFO.PLIST
SLIDE 28
INFO.PLIST
Defines target specific settings that aren’t related to build process: Product version, Product name, Initial Storyboard File, etc.
