This works perfectly and was able to authenticate successfully with the server. old code: ServicePointManager.Expect100Continue = false; ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; IService orderService = new Service(); // private method to load certificate var cert = LoadCertificate(@"....\00050._.1.p12", "pwd"); oIPGApiOrderService.ClientCertificates.Add(cert);

问题 I am testing the iText 7.1.2.0 library to sign pdf files, using a digital certificate or smart card (X509Certificate2) in a C # project. But I'm getting this error when I try to create the IExternalSignature. According to the documentation found (here, here and here), the way to achieve this process is using the BouncyCastle library that allows extracting the primary keys from the digital certificate, however, it is giving me an error and I can not find another way to do it. In the

问题 I'm trying to validate certificate to make sure it has the right keyUsage. But don't see how I can specify my X509KeyUsageFlags.KeyEncypherment usage flag into this application policy. This is the code I have so far. Any one else got this to work? X509Certificate2 tmpCert = new X509Certificate2(Cert); X509Chain ch = new X509Chain(); ch.ChainPolicy.RevocationMode = X509RevocationMode.NoCheck; ch.ChainPolicy.VerificationFlags = X509VerificationFlags.AllowUnknownCertificateAuthority; var kUsage

问题 I want to find certificate from my store but using following code i could not able to get certificate. It always return null. What's wrong with my code?

When I try reading the certificate from a microsoft signed dll e.g. EntityFramework.dll , it works without any problems. I thought it could be because I don't have the certificate in the Trusted Store but even after adding it there, it

问题 Apparently I was asking the wrong question in my earlier post. I have a web service secured with a X.509 certificate, running as a secure web site (https://...). I want to use the client's machine certificate (also X.509) issued by the company's root CA to verify to the server that the client machine is authorized to use the service. In order to do this, I need to inspect the certificate and look for some identifying feature and match that to a value stored in a database (maybe the Thumbprint

问题 How can I convert a DER Format certificate x509 into a human readable format in JavaScript? 回答1: Javascript does not provide a method to parse certificate fields. You need to use a library like forge. I think you need something like this var certAsn1 = forge.asn1.fromDer(certDer) var cert = forge.pki.certificateFromAsn1(certAsn1); console.log(cert.serialNumber); 来源： https://stackoverflow.com/questions/44586556/how-do-i-convert-der-format-certificate-x509-into-human-readable-format

问题 Using framework 4.5.1 and the following requirement, am I doing this right? the URL in the certificate must match the given URL the certificate must be valid and trusted the certificate must not be expired The following passes, but is this sufficient?
