x509certificate

I'm currently trying to generate the subject hash by using the Java Security API and BouncyCastle. Here's what I do, when I use the Openssl Library: openssl x509 -in /Users/Sn0wfreezeDev/Downloads/Test.pem -hash This generates a short 8 digit hash 1817886a This is my Java code X509Certificate cert = CertManager.getCertificate(number, c); MessageDigest sha1 = MessageDigest.getInstance("SHA1"); System.out.println(" Subject " + cert.getSubjectDN()); System.out.println(" Issuer " + cert.getIssuerDN()); sha1.update(cert.getSubjectDN().getName().getBytes()); String hexString = bytesToHex(sha1.digest

I have a web-service which I secured using certificates. Now, I want to identify the client by looking at the certificate thumbprint. This means that I have a list of thumbprints on my service somewhere that are linked to some user. Actually, my first question (a little off-topic) is: is this a good approach or should I still introduce some username password construction? Second question is: how can I get the certificate that the client used to connect to the web-service so I can read the thumbprint at the service side. I did read a lot about it (like this post: How do I get the

I'm writing a small program which will make a GET request to a server using HTTPS and the HttpWebRequest class. The server (obviously) has a server certificate. It also expects the client to provide a certificate. When making the request, however, I get a System.Net.WebException stating that it wasn't possible to establish a secure TLS/SSL connection. I quickly discovered that the server's certificate wasn't valid. Assuming this was what was causing the exception, I tried to accept the invalid certificate (updating the certificate is, unfortunately, not an option) using the code below:

I've recently been put in charge of mocking up an Apple product (iPhone Configuration Utility) in Java. One of the sections I've been a bit stuck on is a part about Exchange ActiveSync. In there, it allows you to select a certificate from your Keychain to use as credentials for your EAS account. After some research, I found that it's actually creating a PKCS12 keystore, inserting the private key of the certificate I selected, and encoding that into XML. So far not a big deal. If I create a .p12 file with Keychain Access it uploads without a problem. But I run into a problem when I try to bring

It's my first question over the web. Hope it will make sense. I have seen several blogs related to this issue over the Web, and I have tried few of the ideas presented in them with no success. Here's my situation: I have a web App calling a WCF web service which then call a Java web service. They are all on different servers. The call between the WCF web service to the java web service is not over https as the certificate will be enough to identify the caller (Message security therefore). Java web service (black box) The Java web service requires to received a signed message and works as per
