How do I extract and decode an ASN.1 message on tvOS?

Question

I would like to extract some information from the App Store receipt in a tvOS app. I thought I could use the Security framework, but the following two header files are missing:

#import <Security/SecAsn1Types.h>
#import <Security/SecAsn1Templates.h>

In the OS X SDK these header files exist. Was ASN.1 support removed from the public tvOS SDK? Do I have to use OpenSSL to handle the receipt?

Answer 1

Security Framework is not included in Apple tvOS framework hence you cannot see this library and imports.

Please follow this link for more clarification about listing of frameworks.

Also for the discussion forum guys already mentioned that in case you need to use the secure storage you can only do it using and CloudKit framework only.
