x509

问题 I'm trying to verify if an specific message is signed with a valid signature from an entity certificate recognized by my own trust anchor. I'm doing this: public static boolean isValid(CMSSignedData signedData, X509Certificate rootCert) throws Exception { CertStore certsAndCRLs = signedData.getCertificatesAndCRLs("Collection", "BC"); SignerInformationStore signers = signedData.getSignerInfos(); Iterator it = signers.getSigners().iterator(); if (it.hasNext()){ SignerInformation signer =

问题 I've generated a self signed certificate using Adobe X, and exported a pfx file (for my private key) along with a .cer file (for the certificate). I then try to collect the certificate, along with the key, but for some reason, OpenSSL is giving the error OpenSSL::X509::CertificateError: not enough data Here is my code require 'openssl' CERTFILE = "test.cer" RSAKEYFILE = "test.pfx" # Open certificate files cert = OpenSSL::X509::Certificate.new(File.read CERTFILE) key = OpenSSL::PKey::RSA.new

问题 I am quite new to C# and especially new to Signing with X509. I have an xml template in which I have to add the certificate used (done) and sign the timestamp (TS-1), the binary security token and the body (id-1). Furthermore, I need to write (e.g. replace placeholders) with the digest value of these 3 elements and add the signature value. However, I do not really understand the concept, e.g. how to do this. I read a couple of websites, e.g. signing a xml document with x509 certificate but I

问题 I am trying to create a digital signature for a block of Text. While I seem to be able to create a signature it is different from the digital test signature as required by our test cases. The code I am using is below. X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser); store.Open(OpenFlags.OpenExistingOnly); X509Certificate2Collection certcol = store.Certificates.Find(X509FindType.FindByIssuerName, "eBusiness Development CA", false); if (certcol.Count > 0) {

问题 Using Rails 3 I want to use an X.509 certificate to sign parts of emails. There is a currently existing answer for Rails 2 at How do I send signed emails from ActionMailer? but it doesn't work on Rails 3. Is it possible to sign emails via ActionMailer in Rails 3? If that is not possible, is it possible to sign emails via sendmail after creating by ActionMailer? 回答1: perhaps it's not the best answer, however here's what I'd do: try to install that plugin (even if it's for rails 2.0.x) tests

问题 I am signing message using digital certificate in a asp.net web service using below code. Signing is working fine expect signedMessage.ComputeSignature line is taking up to 30 to 40 seconds because of this i am face timeout exception. The same code when i am running under windows forms application is producing result in fraction of second. Any clue or help. public static string Encrypt(string fullMessage, string certificateName, bool deAttch) { X509Certificate2 signer = GetCertificate

问题 I want to read the contents of a CSR in C#. However, I haven't found any way to do it in C#. What I've found was the namespace System.Security.Cryptography.X509Certificates , but it only handles existing certificates, not certificate requests. Can anyone give me an hint about it? Thanks in advance. 回答1: There is a way, the CertEnroll library which comes with Windows (although I can't say how far back it's been there) allows you to load certificate requests and have them parsed. First you need

问题 public class CustomTrustManager implements X509TrustManager { private X509TrustManager trustManager; // If a connection was previously attempted and failed the certificate check, that certificate chain will be saved here. private Certificate[] rejectedCertificates = null; private Certificate[] encounteredCertificates = null; private KeyStore keyStore = null; private Logger logger; /** * Constructor * * @param loggerFactory * see {@link InstanceLoggerFactory} */ public CustomTrustManager

问题 I'm having problems using openssl to create a x509 certificate containing a crl distribution point for testing. I've checked the documentation and found the configuration setting crlDistributionPoints for this purpose. Unfortunately openssl always generates x509 version 1 certificates without instead of version 3 certificates with the crl distribution point. I'm sure something is wrong with my command or the configuration but reading the documentation carefully and playing around with the

问题 Background: I am writing a client utility which is capable of connecting to a remote server using SSL/TLS. The client uses OpenSSL to perform the SSL/TLS transactions and I would like to allow users to specify authorized CA Certs (in the case of self signed certs or private CA setups) used to sign the server's certificate. I plan on using the cert's fingerprint, common name, and validity dates to allow the user to quickly view the certs the client uses to validate servers. Question: How do
