x509certificate

I have a .NET (c#) application which uses the x509Certificate2 in the 'my' Certificate Store, originally coming from an eToken device. When I use the certificate (to decrypt data or use it as a clientcert for web requests), it will ask for the device PIN once. After that, it is cached, the user isn't bothered with the password request every xx minutes. Now, I have multiple processes, that all use the certificate. Each of these processes will request the device PIN. (the cache seems to be per process). Is there an easy way around this? Can I 'cache' it somewhere, so that every process can

I am trying to make a X.509 certificate. I am using makecert.exe to make this. I use this command to make my X.509 certificate makecert.exe -sr LocalMachine -ss My -a sha1 -n CN=MyServerCert -sky exchange –pe But i don`t know there X.509 certificate is storeing. I need to use this X.509 certificate in my c# code. The code is : host.Credentials.ServiceCertificate.Certificate = new X509Certificate2("MyServerCert.p12", "password"); But i don`t know what is password and it throw this exception "The system cannot find the file specified." I always use the SelfCert tool from PluralSight. You can

I have created a self-signed certificate with Java code and added into KeyStore. Now I want to export Private key and Certificate created, into a file in PEM format. Is it possible to achieve this without any third party library ? Below is the code I use for creating self-singed certificate. public void createSelfSignedSSLCertificate() { try { final CertAndKeyGen keypair = new CertAndKeyGen("RSA", "SHA1WithRSA", null); final X500Name x500Name = new X500Name(commonName, organizationalUnit, organization, city, state, country); keypair.generate(keysize); final PrivateKey privKey = keypair

I want to parse a X.509 certificate in php. The certificate is in DER-encoded X.509 format. I tried using openssl_x509_parse method in php, but its not working. The certificate data is a valid data received after firing a command in mdm for CertificateList. I am using the below code: $data = 'MIIDizCCAnMCCQDCpCAUbA2P4TANBgkqhkiG9w0BAQUFADBrMSIw IAYDVQQKDBkqLnNtYXJ0c291cmNpbmdnbG9iYWwubmV0MSEwHwYD VQQLDBhEb21haW4gQ29udHJvbCBWYWxpZGF0ZWQxIjAgBgNVBAMM GSouc21hcnRzb3VyY2luZ2dsb2JhbC5uZXQwHhcNMTIwNTI5MTM1 NTU0WhcNMTMwNTI5MTM1NTU0WjCBozELMAkGA1UEBhMCTlkxCzAJ

How can we use X509_verify(). I have two certificates. The first certificate is the Root Certificate which signed the next certificate (which is my Certificate). So I want to check if my certificate is signed by the root certificate using x509_verify() in C++. My goal is to keep the code simple and Understandable so I can also put it online. Signature of X509_verify is int X509_verify(X509 * x509, EVP_PKEY * pkey); Suppose of you have root certificate in root and your certificate in mycert; X509 * root; X509 * mycert; //Get root certificate into root //Get mycert into mycert. //Get the public
