Signing content for apple passbook in c#

Question

            ContentInfo contentInfo = new ContentInfo(File.ReadAllBytes(@\"D:\\prj\\t         


        

Answer 1

For those tearing their hair out after renewing their certificate and finding it doesn't work, you now need to add the 'signed-time' attribute to the signature. Hence:

var oid = new Oid("1.2.840.113549.1.7.2");
ContentInfo contentInfo = new ContentInfo(oid, manifest);

var signedCms = new SignedCms(contentInfo, true);
var signer = new CmsSigner(SubjectIdentifierType.IssuerAndSerialNumber, myX509certificate);
signer.IncludeOption = X509IncludeOption.EndCertOnly;
signer.Certificates.Add(appleWwdrCertificate);

// new requirement to add 'signing-date'
signer.SignedAttributes.Add(new Pkcs9SigningTime(DateTime.Now));
signedCms.ComputeSignature(signer);

bytes[] signature = signedCms.Encode();

Try loading the Certificates from The Windows Certificate store,

I've created an OSS library for .Net that handles all of this for you. You just need your own Passbook certificate and the main Apple certificate.
