x509certificate

问题 I am having a chain of X509Certificates starting with user certificate and ending with trusted CA certificate. For the test, I am experimenting with Google certificates. I want to check the revocation status of every certificate in Certificate chain. I am using following code: public static boolean isCertChainValid(ArrayList<X509Certificate> certificateList) { try { CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509"); CertPath certPath = certificateFactory

问题 I have an X509Certificate accessed by a variable ... when i try to get the details of the certificate i manage to get the CriticalExtensions value easly by the functions provided. however what i'm trying to reach is the none critical extension which is stored in certifcate and represented by Object ID # 2.5.29.32 what i'm trying to access is the policy identifier number which is show in this image: http://i.stack.imgur.com/xo8zX.png i used the following function cert.getExtensionValue("2.5.29

问题 I created one root, one intermediate certificate. Then I signed my Extended Certificate, but it did not. I added root and intermediate certificates to the browser and to the computer' keystore. I see the word "Secure" but I want to see my name in the green bar. What is the policy for generating one extended certificate with OpenSSL? certificatePolicies=ia5org,1.2.3.4,1.5.6.7.8,@polsect [polsect] policyIdentifier = 1.3.5.8 CPS.1="https://jitc.rahmican.com.tr"; userNotice.1=@notice [notice]

问题 I have my X509Certificate stored in a database (in byte[] ) so that my application can retrieve the certificate and use it to sign my JWTs. My x509Certificate is passed off a .pfx file that I generated on my machine, however now it sits in a database as a string of bytes. My application works perfectly fine locally when I run it. The application can correctly create an instance of that X509Certificate2 and use it for my requirements, however the problem arises when I try to use it in my

问题 I have written a program (obviously COPIED from the net, and modified it little according to my needs!) for file download/upload using apache ftp api and by creating a local server using Filezilla server. Everything is working FINE . The problem is I didn't get the part where we have to create a trust manager. Code: FTPSClient ftpsClient= null; SSLContext sslContext = SSLContext.getInstance(protocol); TrustManager tm = new X509TrustManager() { public X509Certificate[] getAcceptedIssuers() {

问题 I want to know if it is possible to sign data using a smart card's private key without resorting to a java applet or activex control. I am tantalizingly close! Our environment is: AD Domain PKI infrastructure/smart cards (PIV) I knocked up a simple ASP.NET (.net 4.0) web forms app with: Windows Authentication on, Anonymous off Identity Impersonate on With the smart card in the reader I can easily enumerate the certificates on the logged-in user's smart card (StoreLocation.CurrentUser).

问题 Exception: MessageSecurityException: Cannot resolve KeyInfo for verifying signature: KeyInfo 'SecurityKeyIdentifier I have to set up a WCF service to receive SOAP calls from a Java client that is sending signed content with the following header: <soap:Header> <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" soap:mustUnderstand="1"> <ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#" Id="Signature-2"> <ds:SignedInfo xmlns:ds=

问题 I have a RemoteCertificateValidationCallback function called by SslStream.AuthenticateAsClient, which is passed an X509Certificate object. I'd like to extract the name from that certificate, such that had I passed that string into AuthenticateAsClient, it would have passed. (Assuming no other issues.) (Note: The Subject property contains the domain name, but it's inside a "CN=..., S=..." etc formatted string.) See also: How to extract CN from X509Certificate in Java? (Asks a similar question

问题 I have followed this guide Self-signed SSL connection using PyMongo, by Wan Bachtiar to create three .pem files; server.pem, client.pem and ca.pem. I am using Ubuntu 16.04 and MongoDB v3.2.11. The purpose is to secure the MongoDB before opening it to the public internet. lets start the mongod: $ mongod --auth --port 27017 --dbpath /data/db1 --sslMode requireSSL --sslPEMKeyFile /etc/ssl/server.pem --sslCAFile /etc/ssl/ca.pem --sslAllowInvalidHostnames & Output: root@tim:/etc/ssl# 2017-01-13T12

问题 I'm developing ASP.NET 4.0 web application, and I want to read the current user certificates from X509Store. Reading the LocalMachine certificates works fine, but if I set the StoreLocation to CurrentUser, it gives me an empty collection. The following code works fine : X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine); // StoreLocation.CurrentUser store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly); I've checked my personal store (via certmgr.mmc) and I'm sure
