Support for Pushsharp Apple Key authentication push notification

Question

Does pushsharp support Apple's new approach for sending APNs using the Apple Authentication Key (which never expires) instead of using certificates? Can I use it with pushsharp? If not, is there another C # library to support it?

Answer 1

here you are:

private string GetToken() { var algorithm = "ES256"; var teamID = "teamID"; var apnsKeyID = "apnsKeyID"; var apnsAuthKeyPath = @"apnsAuthKeyPath"; var epochNow = DateTimeOffset.Now.ToUnixTimeSeconds(); var header = new Dictionary<string, object>() { { "alg", algorithm }, { "kid" , apnsKeyID } }; var payload = new Dictionary<string, object>() { { "iss", teamID }, { "iat", epochNow } }; var privateKey = GetPrivateKey(apnsAuthKeyPath); var token = Jose.JWT.Encode(payload, privateKey, algorithm: Jose.JwsAlgorithm.ES256, extraHeaders: header); return token; } private CngKey GetPrivateKey(string apnsAuthKey) { using (var reader = File.OpenText(apnsAuthKey)) { var ecPrivateKeyParameters = (ECPrivateKeyParameters)new PemReader(reader).ReadObject(); var x = ecPrivateKeyParameters.Parameters.G.AffineXCoord.GetEncoded(); var y = ecPrivateKeyParameters.Parameters.G.AffineYCoord.GetEncoded(); var d = ecPrivateKeyParameters.D.ToByteArrayUnsigned(); return EccKey.New(x, y, d); } } 

then you can just call the submit method in apns.

Where should we place this code?
