x509

I've got an X509Certificate2 containing a public key. I've got an RSACryptoServiceProvider (which came from calling SignedXml.CheckSignatureReturningKey ), also containing a public key. I want to find out if one came from the other. How can I compare the two? You can compare the PublicKey property of signing certificates in the SignedXml.KeyIfo with signing key output from SignedXml.CheckSignatureReturningKey . This C# extension method does the job for me: public static bool CheckSignatureReturningCertificate(this SignedXml signedXml, out X509Certificate2 signingCertificate) {

I have a SSL/TLS client program using OpenSSL in C++ programming language. I am looking for methods to validate server certificate ( X509 ) returned by SSL_get_peer_certificate function call. Also, I have my own CA certificate loaded using SSL_CTX_load_verify_locations function. The CA certified the server certificate. I am able to make SSL session to my server. Now, i want to validate server certificate received during SSL handshake using my own CA. I couldn't find a way to do it in C or C++. #include <iostream> #include <string.h> #include <unistd.h> #include <sys/socket.h> #include <resolv

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 am newbie in openSSL library and PKI . I have simple question for openSSL experts. Does anybody know how to create certificates for code samples in this article "An Introduction to OpenSSL programming (Part I/II)" by Eric Rescorla www.rtfm.com/openssl-examples/part1.pdf www.rtfm.com/openssl-examples/part2.pdf I have downloaded source code from http://www.rtfm.com/openssl-examples The problem is that certificates are expired and I don't know how to create new root certificate. How to create root certificate? How to create certificates for client and server app? Wich ciphering algorithm should

I manage the Domain Controllers centrally, but the site admins manage their own digital senders locally. I can easily export an X509 certificate (private key not needed) with the whole chain from a Windows Server 2008 R2 Domain Controller to a p7b file through the wizard: ~~~~~~~~~~~~~~~~~ ...5. The Certificate Export Wizard opens. Click Next. In the Export File Format dialog box, do the following: a. Select Cryptographic Message Syntax Standard – PKCS #7 Certificates (.P7B). b. Check Include all certificates in the certification path if possible. c. Click Next. In the File to Export dialog

I'm trying to publish some data on the Azure IoT hub using Mqtt. I've succesfully published some data, using a SAS token. But my customer wants a x509 self generated & self signed certificate. Azure is supporting this, but doesn't give much information about it. ( https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-security#supported-x509-certificates ) A self-generated and self-signed X-509 certificate. A device manufacturer or in-house deployer can generate these certificates and store the corresponding private key (and certificate) on the device. You can use tools such as

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
