由 余生颓废 提交于 2019-11-27 12:02:59
For a secure application I need to select a certificate in a dialog. How can I access certificate store or a part of it (e.g. storeLocation="Local Machine" and storeName="My" ) using C# and get a collection of all certificates from there? Thanks in advance for your help. acejologz X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine); store.Open(OpenFlags.ReadOnly); foreach (X509Certificate2 certificate in store.Certificates){ //TODO's } Try this: //using System.Security.Cryptography.X509Certificates; public static X509Certificate2 selectCert(StoreName store, StoreLocation

问题 Let's say I have three certificates (in Base64 format) Root | --- CA | --- Cert (client/signing/whatever) How can I validate the certs and certificate path/chain in C#? (All those three certs may not be in my computer cert store) Edit : BouncyCastle has the function to verify. But I'm trying not to use any third-party library. byte[] b1 = Convert.FromBase64String(x509Str1); byte[] b2 = Convert.FromBase64String(x509Str2); X509Certificate cer1 = new X509CertificateParser().ReadCertificate(b1);

How does an SSL certificate chain bundle work?

由 泄露秘密 提交于 2019-11-27 10:07:23
问题 I've created a chain hierarchy like this. root-ca ==> signing-ca ==> subordinate-ca ==> server It is mentioned to create chain bundle, the lowest should go first. $ cat server.crt subordinate-ca.crt signing-ca.crt > server.pem But verification fails. $ openssl verify -CAfile root-ca.crt server.pem error 20 at 0 depth lookup:unable to get local issuer certificate However, if I change the order it seems to work. $ cat signing-ca.crt subordinate-ca.crt server.crt > server.pem $ openssl verify

I have a p12 certificate, that I load it in this way: X509Certificate2 certificate = new X509Certificate2(certName, password, X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable); It is loaded correcty, in fact If i do certificate.PrivateKey.ToXmlString(true); it returns a complete xml without errors. But If I do: try { X509Chain chain = new X509Chain(); var chainBuilt = chain.Build(certificate); Console.WriteLine("Chain building status: "+ chainBuilt); if (chainBuilt == false) foreach (X509ChainStatus chainStatus in chain.ChainStatus) Console

Accessing uploaded certificates in azure web sites

由 空扰寡人 提交于 2019-11-27 07:36:39
When I was using the web role I was just uploading the certificate in azure portal and I was able to see it .Now I have switched to the website in azure and I uploaded the certificate in the azure management portal but my code does not see it at all. Is there some configurations we need to do or some other way to access uploaded certs in azure web sites. This is how I am trying to access the uploaded cert . private List<string> GetAvailableCertificatesFromStore() { var list = new List<string>(); var store = new X509Store(StoreName.My,StoreLocation.LocalMachine); store.Open(OpenFlags.ReadOnly);

How do I use m2crypto to validate a X509 certificate chain in a non-SSL setting

由 白昼怎懂夜的黑 提交于 2019-11-27 07:00:50
问题 I'm trying to figure out how to, using m2crypto, validate the chain of trust from a public key version of a X509 certificate back to one of a set of known root CA's when the chain may be arbitrarily long. The SSL.Context module looks promising except that I'm not doing this in the context of a SSL connection and I can't see how the information passed to load_verify_locations is used. Essentially, I'm looking for the interface that's equivalent to: openssl verify pub_key_x509_cert Is there

What does the 'Z' mean in Unix timestamp '120314170138Z'?

由 夙愿已清 提交于 2019-11-27 06:34:56
I have an X.509 certificate which has the following 2 timestamps: ['validFrom'] = String(13) "120314165227Z" ['validTo'] = String(13) "130314165227Z" What does the postfix character 'Z' mean. Does it specify the timezone? Yes. 'Z' stands for Zulu time, which is also GMT and UTC. From http://en.wikipedia.org/wiki/Coordinated_Universal_Time : The UTC time zone is sometimes denoted by the letter Z—a reference to the equivalent nautical time zone (GMT), which has been denoted by a Z since about 1950. The letter also refers to the "zone description" of zero hours, which has been used since 1920
