x509certificate2

问题 I've created an ECDSA CSR using certreq, now I want to import the certificate into my local store and pair it with the private key. I can import RSA public keys and pair them up no problem, and can import ECDSA certificates but they lack their private key... I've looked into all kinds of methods and properties on every class I could see - None of them seem to have a straightforward way to "set" the private key when it's ECDsa - One promising method is the "ECDsaCertificateExtensions

问题 Need to protect client-server communication. I was found a nice approach in .Net Core to generate X509 Certificates ( Self-Signed). But it's really lack of any information how to work with Certificate Revocation List in .Net Framework. Will be appreciate for answers to those questions : How to create CRL file with .Net ( Without BouncyCastle ) ? Can it be created as any text file and signed after? If yes, what is the format of columns? Is I'm right understanding that CRL file could be added

问题 I don't really understand how to work with PKCS#7 messages. I sign some byte array with a X509Certificate2 I have and get also a byte array. byte[] data = new byte[5] { 110, 111, 112, 113, 114 }, signedData; X509Certificate2 cert = new X509Certificate2(certPath, password); ContentInfo content = new ContentInfo(data); SignedCms envelope = new SignedCms(content); CmsSigner cmsSigner = new CmsSigner(cert); envelope.ComputeSignature(cmsSigner); signedData = envelope.Encode(); The signedData is

问题 I have been doing some research to see if there is a way to script this functionality and I cant seem to find where these certs are actually stored. I see the other articles on "deleting certificates from store", but I think these are causing me more confusion. If I run a search like get-childitem -path cert:\CurrentUser , I don't see the Other People location. But, I am able to see the location in certmgr.msc . I have also checked the reg locations outlined here: https://technet.microsoft

问题 I am fetching my certificate from Azure Key Vault using GetSecretAsync() method and then I am expecting to get the byte[] of the private key and the certificate eventually. I have my application in .netcore3.1 This is how my code looks like : var certWithPrivateKey = Client.GetSecretAsync(ConfigurationSettings.AppSettings["AKVEndpoint"], ConfigurationSettings.AppSettings["CertName"]).GetAwaiter().GetResult(); var privateKeyBytes = Convert.FromBase64String(certWithPrivateKey.Value);

问题 I try to use X509Certificate2.Verify() function to check if a certificate chain is valid. The Verify function returns false and the ChainElementStatus returns "RevocationStatusUnknown". Is there a way to use the Verify function without the check of the RevocationStatus? The RevocationStatus can't be checked without internet connection? Is there a other function to check the chain and certificates wihtout the RevocationStatus? A dirty solution, is to check if the RevocationStatus is the only

问题 I want to create a self signed certificate with RSA algorithm keysize 2048 with subject key identifier. I know we made some some default change in openssl.conf . What i suppose to change? genrsa -des3 -out mcedt.key 2048 req -new -key mcedt.key -out mcedt.csr CN = server.test , OU =, O =, L = Toronto, S = ontario , C = can x509 -req -days 365 -in mcedt.csr -signkey mcedt.key -out mcedt.crt pkcs12 -export -in mcedt.crt -inkey mcedt.key -out mcedt.pfx 回答1: You could create an extension file

问题 I am working with creating X509Certificate2 certificate in my C#.net application. While creating certificate, how to set the issuer name? currently issuer name shows same as subject name. Please help. 回答1: Hmm. Finally I have used Bouncy Castle dll to create certificates.Using this, there is a method to set issuer name. This is the fully code to generate x509Certificate and to store into Trusted People store: private X509Certificate2 GeneratePFXFile(string certificate,string company,string
