Apple Sign In "invalid_client", sign JWT for authentication using PHP and openSSL

QUESTION

Apple Sign In "invalid_client", sign JWT for authentication using PHP and openSSL

Asked 2020-Mar-12 at 13:37

I'm trying to implement Apple sign in into an Android App using this library. The main flow is described in the documentation: the library returns an authorization code on the Android side. This authorization code has to be sent to my backend which, in turn, sends it to the Apple servers in order to get back an access token.

As described here and here, in order to obtain the access token we need to send to the Apple API a list of parameters, the authorization code and a signed JWT. In particular, JWT needs to be signed with a ES256 algorithm using a private .p8 key which has to be generated and downloaded from the Apple developer portal. Apple doc

Here is my PHP script:

As indicated here, the problem is actually in the signature generated by openSSL.

Using ES256, the digital signature is the concatenation of two unsigned integers, denoted as R and S, which are the result of the Elliptic Curve (EC) algorithm. The length of R || S is 64.

The openssl_sign function generates a signature which is a DER-encoded ASN.1 structure (with size > 64).

The solution is to convert the DER-encoded signature into a raw concatenation of the R and S values. In this library a function "fromDER" is present which perform such a conversion:

Install sign-in-with-apple-button-android

First, follow Apple's instructions to set up Sign In with Apple in your iOS app and for a web service. It is the web service setup that you'll use from Android, but you need both. More setup is necessary for backend operations, but the above is all you need to use this library. For more detail, you can read Aaron Parecki's walkthrough, What the Heck is Sign In with Apple?.
An App ID including the Sign In with Apple capability
A Service ID using the App ID as its primary mapped to a domain you control which Apple has verified including at least one Return URL
A client ID, which you entered as the Identifier field of the Service ID.
A redirect URI, which you entered as the Return URL.
Include as a dependency using Gradle:. Snapshot versions are also available.
