x509certificate

I have a SAML assertion that I wish to authenticate in .Net using WSSecurityTokenSerializer . I've got the key-chain and SAML XML, despite a few issues . First I get the SAML assertion from the HTTPS POST: // spec says "SAMLResponse=" string rawSamlData = Request["SAMLResponse"]; // read the base64 encoded bytes byte[] samlData = Convert.FromBase64String(rawSamlData); // read back into a UTF string string samlAssertion = Encoding.UTF8.GetString(samlData); // get the SAML data in an XML reader var assertionPostStream = new StringReader(samlAssertion); var reader = XmlReader.Create

I need to build a certificate chain on Windows, from an X.509 smart card cert through one or more intermediate CAs to a root CA. That's easy when the CA certs are in a JKS keystore, but I need to use the Windows keystores as well. I can get the root CA cert from "Windows-ROOT", but I can't get to the "Intermediate Certification Authorities" keystore. Has anyone done this? Thanks! The SunMSCAPI Cryptographic provider does only support two keystores: Windows-MY (personal certificate store) and Windows-ROOT (trusted authorities certificate store), thus I don't thinks it is possible to directly

I am currently overriding X509TrustManager to allow all certs as a temporarily 'solution' (an unsafe one at that). I am trying to figure out how I would go about adding in so it accepts just a specific cert that I'm having issues with until a proper fix can be done (which is out of my hands at the moment). Here is the current code. TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() { @Override public java.security.cert.X509Certificate[] getAcceptedIssuers() { return null; } @Override public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String

I have a web app that requires a client to send it's certificate and the server has to validate the certificate(i.e see if the issuer is a valid issuer and present in the server's truststore). Here is the code : FileInputStream fin=new FileInputStream("C:/trustedca"); KeyStore anchors = KeyStore.getInstance("JKS","SUN"); anchors.load(fin, "server".toCharArray()); X509CertSelector target = new X509CertSelector(); FileInputStream fin1=new FileInputStream("C:/client.crt"); CertificateFactory cf=CertificateFactory.getInstance("X.509"); X509Certificate cert=null; while (fin1.available() > 0) {

I'm having a problem when I use the method X509Store.Certificates.Find public static X509Certificate2 FromStore(StoreName storeName, StoreLocation storeLocation, X509FindType findType, string findValue) { X509Store store = new X509Store(storeName, storeLocation); store.Open(OpenFlags.ReadOnly); try { //findValue = "7a6fa503ab57b81d6318a51ca265e739a51ce660" var results = store.Certificates.Find(findType, findValue, true); return results[0]; } finally { store.Close(); } } In this case the Find Method returns 0 results ( results.Count == 0 ), but if I put the findValue as constant the method find

I'm trying to install certificates without prompting the user. I know this is not good practice, but that's what PM wants. Using KeyChain.createInstallIntent() , I can get Android to launch the certificate installation dialog by calling startActivity . However, when I pass the intent to sendBroadcast , nothing happens. Maybe the platform doesn't support this for security reasons? String CERT_FILE = Environment.getExternalStorageDirectory() + "/test/IAT.crt"; Intent intent = KeyChain.createInstallIntent(); try { FileInputStream certIs = new FileInputStream(CERT_FILE); byte [] cert = new byte[
