Getting SignerInfo.SignedAttributes throws an exception

[AlexeyAKat]

The following test code works on Windows and throws an exception on linux:

var contentInfo = new ContentInfo(new Oid("1.2.840.113549.1.7.1"), data);
var signedCms = new SignedCms(contentInfo, true);

// signerCert - X509Certificate2 object of Gost certificate
var cmsSigner = new CmsSigner(signerCert) { IncludeOption = X509IncludeOption.EndCertOnly };

cmsSigner.SignedAttributes.Add(new Pkcs9SigningTime());
signedCms.ComputeSignature(cmsSigner);

var signerInfo = signedCms.SignerInfos[0];

// throws an exception
var signedAttributes = signerInfo.SignedAttributes;

To work with constructors with implicit oids (like ContentInfo(), SignedCMS()) you need to update cryptoprovider to lates one. You can download it from this page

Thanks, it worked! Installed version of Crypto-Pro CSP: 5.0.11732 .
