x509certificate

I am trying to generate a X.509 Certificate using Bouncy Castle Java API. I found sample code at: http://www.bouncycastle.org/wiki/display/JA1/X.509+Public+Key+Certificate+and+Certification+Request+Generation However, after compile the below codes, JVM shows an error message as shown below Could not find the main class: org.bouncycastle.util.AllTests. Program will exit. Note that org.bouncycastle.util.AllTests is inserted into the Java build path. How can I fix my code to work properly? import java.math.BigInteger; import java.util.Date; import org.bouncycastle.asn1.ASN1Object; import org

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("2.5.29.32"); but it doesn't give me the value .. anyone can tell me what i'm doing wrong ? P.S: i'm using the

Create a selfsigned java keystore and certificate file using keytool utility. Am able to add the certificate into windows trust store by going to certificate console by using mmc.exe command. But is there anyway to add the certificate into windows trust store programmatically. And also required the same things for MAC system. Appreciate for any suggestions. Below is code snippet for Windows/MAC to add certificate in their trust store. Window: KeyStore root = KeyStore.getInstance("Windows-ROOT","SunMSCAPI"); root.load(null,null); /* certificate must be DER-encoded */ FileInputStream in = new

I have a .pfx certificate file on my computer. I want to to encrypt a message with its public key, and then decrypt it with the private. Also I want to sign another message with its private key, and then check the signature. And I need to get the information about the sertificate the message was signed with from that message. How can I do it using System.Security.Cryptography? You can open the PFX in .NET, like the following: var path = <YOUR PFX FILE PATH>; var password = <YOUR PASSWORD>; var collection = new X509Certificate2Collection(); collection.Import(path, password, X509KeyStorageFlags

I have been given a p12 public/private key signed by a certain CA. I have a local tomcat server that I am doing development work on. I am new to security but I believe that need to get the CA public cert into my tomcats truststore. (I am trying to get x509 certs working with CAS) How do I get my tomcat (and JVM) to trust this CA? Is there a way to get the CA public cert out of a p12 and into my tomcat truststore? (I have also exported the cert from firefox to get a PEM file for the CA) I see a lot of posts for jsk to pem, but not the other way round. I just need the CA. (I think) :) Bruno

I am trying to load certificate file into certificate object, but I am getting the below exception. java.security.cert.CertificateParsingException: invalid DER-encoded certificate data at sun.security.x509.X509CertImpl.parse(X509CertImpl.java:1701) at sun.security.x509.X509CertImpl.<init>(X509CertImpl.java:303) at sun.security.provider.X509Factory.parseX509orPKCS7Cert(X509Factory.java:532) at sun.security.provider.X509Factory.engineGenerateCertificates(X509Factory.java:417) at java.security.cert.CertificateFactory.generateCertificates(CertificateFactory.java:427) Below is the code I am using

I have certificate file and private key file in pem format. Is it possible to load these files into Java keystore using Java code with default libraries that comes with JDK and not with third party libraries. When I tried googling, I am able to find only files which are in .der format to import into java keystore using java code. http://knowledge-oracle.blogspot.in/2009/02/import-private-key-and-certificate-in.html Is it possible to load key and certificate file which is in pem format into java keystore through java code without converting to .der format ? It is possible but not without using
