  • Create and use intermediate certificate authority on Windows Server 2012?

    - by Sid
    Background: Server OS is Windows Server 2012. GUI is installed as we come upto speed with powershell. Setup is staging, not production (yet). We have our (internal, domain limited) Root CA installed. I would like to take the Root CA offline to secure storage but before that I'd like to setup an intermediate CA which can take over actual live, online (int-RA-net) functionality Can someone guide me covering: creating the intermediate CA certificate request installing the intermediate CA certificate on domain controller (certification authority role already installed with Root CA online right now) use the intermediate CA to generate a certificate (any use certificate, just for demonstration purposes) Obviously this certification chain would be invalid on computers outside our domain (self trusted root - our root certificate is NOT from common 3rd parties). This last point is NOT a problem.

  • Digital Certificate Parsing Library in C++?

    - by Sherwood Hu
    I used Crypto++ for my application. However it lacks a digital certificate parser. I know that openSSL has one, but I have to learn the whole library again. Is there some parsing library existing for C++? All I want is to read the certificate and extract some fields, including the public key.

  • Verify a X.509 certificate with Java ME and Bouncy Castle

    - by Dino
    Hi, Can anybody point me to an example of verifying a X.509 certificate with Bouncy Castle under Java ME? I can see how to easily do this in Java SE code with java.security.cert.Certificate.verify(), but I could not find an equivalent method in the lightweight BC API. Thanks in advance! Cheers Dino

  • Decoding http response with certificate

    - by Tim
    Hi all, I'm new to php and I need to authenticate to a SSO server. The SSO server is a .Net one, using a SSL certificate. When I go back from the SSO server, the response is encoded. I have the key of the certificate of course, but how could I decrypt the response ?

  • Windows Server 2008 R2 creating a multi-year client certificate using the IIS certsrv page while deploying SSTP VPN

    - by Warren P
    I am trying to follow instructions on Technet about deploying a Standard (non-enterprise) SSTP based VPN) that were originally written for Server 2008, but I am using Server 2008 R2, I have gotten as far as the part where it asks you to create a request a Server Authentication certificate. I have deployed IIS, and Active Directory Certificate Services, and chose "Standalone" and "Standard" (non-enterprise) Certificate Authority because I don't have an OID and don't think I should have to get one for a simple deployment of SSTP. The resulting certificates made by the Certification Authority "Issue" command, only have a 1 year period of validity, I want a multi-year certificate. At no point in this process is there any way to input this information unless it's through the Attributes text input area on the Advance Certificate Request page, which appears to be generated using an old ActiveX control, which means I can only do this using the workarounds in the article that I linked at the top, and only using Internet Explorer. Update:: It may be that this question is pointless since self-signed keys do not appear to work, when I try them, using Windows 8 as the VPN client. The problem is that the keys that are self-created by the technique shown here do not have any Certificate Revocation Server URLs and so you get an error "The revocation function was unable to check revocation", and the VPN connection fails.

  • Android: debug certificate expired error

    - by Bill Osuch
    I started up Eclipse today, created a new project, and immediately had an error before I had changed a single line: Error generating final archive: Debug Certificate expired on 11/12/11 When installed, the Android SDK generates a "debug" signing certificate for you in a file called "debug.keystore". Eclipse uses this certificate rather than forcing you to create a new one for every project. In older versions of Eclipse, the certificate was only valid for 365 days, but as I understand it the default has been changed to 30 years in newer versions. If for whatever reason you don't want to upgrade Eclipse, you can manually delete the certificate to for Eclipse to generate a new one. You can find the location in Preferences -> Android -> Build -> Default debug keystore (mine was in C:\Users\myUserName\.android\); just delete the "debug.keystore" file, then go back into Eclipse and Clean the project to generate a new file.

  • certificate issues running app in windows 7 ?

    - by Jurjen
    Hi, I'm having some problems with my App. I'm using 'org.mentalis.security' assembly to create a certificate object from a 'pfx' file, this is the line of code where the exception occurs : Certificate cert = Certificate.CreateFromPfxFile(publicKey, certificatePassword); this has always worked and still does in production, but for some reason it throws an exception when run in windows 7 (tried it on 2 machines). CertificateException : Unable to import the PFX file! [error code = -2146893792] I can't find much on this message via google, but when checking the EventViewer I get an 'Audit Failure' every time this exception occurs: Event ID = 5061 Source = Microsoft Windows Security Task Category = system Integrity Keywords = Audit Failure Cryptographic operation. Subject: Security ID: NT AUTHORITY\IUSR Account Name: IUSR Account Domain: NT AUTHORITY Logon ID: 0x3e3 Cryptographic Parameters: Provider Name: Microsoft Software Key Storage Provider Algorithm Name: Not Available. Key Name: VriendelijkeNaam Key Type: User key. Cryptographic Operation: Operation: Open Key. Return Code: 0x2 ` I'm not sure why this isn't working on win 7, I've never had problems when I was running on Vista with this. I am running VS2008 as administrator but I guess that maybe the ASP.NET user doesn't have sufficient rights or something. It's pretty strangs that the 'Algorithm name' is 'Not Available' can anyone help me with this... TIA, Jurjen de Groot

    - by allenzzzxd
    Hello, guys, I have to write these codes in c. I have already generate the certificate of one terminate t1: t1.pem, which is generated by openssl. The communication between the terminates t1 and t2 has been established via socket in c. Now I want to send this certificate to another terminate t2.and I want t2 to receive the certificate, verify it and answer with an acceptance to t1. When t1 get this acceptance, it will the rest of stuffs.. But I don't know how to do these things. For example, I transmit t1.pem as a string? But in t2 side, how can I do to verify? I know there are functions in openssl to do so, but I'm not so clear about it. At last, normally, the acceptance should be like how? @[email protected] lot of questions here.. sorry...if someone could give me some guide.. Thanks a lot in advance!

  • How to give ASP.NET access to a private key in a certificate in the certificate store?

    - by thames
    I have an ASP.NET application that accesses private key in a certificate in the certificates store. On Windows Server 2003 I was able to use winhttpcertcfg.exe to give private key access to the NETWORK SERVICE account. How do I give permissions to access a Private Key in a certificate in the certificate store (Local Computer\Personal) on a Windows Server 2008 R2 in an IIS 7.5 website? I've tried giving Full Trust access to "Everyone", "IIS AppPool\DefaultAppPool", "IIS_IUSRS", and everyother security account I could find using the Certificates MMC (Server 2008 R2). However the below code demonstrates that the code does not have access to the Private Key of a certificate that was imported with the private key. The code instead throws and error everytime the private key property is accessed. Default.aspx <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <%@ Import Namespace="System.Security.Cryptography.X509Certificates" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:Repeater ID="repeater1" runat="server"> <HeaderTemplate> <table> <tr> <td> Cert </td> <td> Public Key </td> <td> Private Key </td> </tr> </HeaderTemplate> <ItemTemplate> <tr> <td> <%#((X509Certificate2)Container.DataItem).GetNameInfo(X509NameType.SimpleName, false) %> </td> <td> <%#((X509Certificate2)Container.DataItem).HasPublicKeyAccess() %> </td> <td> <%#((X509Certificate2)Container.DataItem).HasPrivateKeyAccess() %> </td> </tr> </ItemTemplate> <FooterTemplate> </table></FooterTemplate> </asp:Repeater> </div> </form> </body> </html> Default.aspx.cs using System; using System.Security.Cryptography; using System.Security.Cryptography.X509Certificates; using System.Web.UI; public partial class _Default : Page { public X509Certificate2Collection Certificates; protected void Page_Load(object sender, EventArgs e) { // Local Computer\Personal var store = new X509Store(StoreLocation.LocalMachine); // create and open store for read-only access store.Open(OpenFlags.ReadOnly); Certificates = store.Certificates; repeater1.DataSource = Certificates; repeater1.DataBind(); } } public static class Extensions { public static string HasPublicKeyAccess(this X509Certificate2 cert) { try { AsymmetricAlgorithm algorithm = cert.PublicKey.Key; } catch (Exception ex) { return "No"; } return "Yes"; } public static string HasPrivateKeyAccess(this X509Certificate2 cert) { try { string algorithm = cert.PrivateKey.KeyExchangeAlgorithm; } catch (Exception ex) { return "No"; } return "Yes"; } }

  • Another developer revoked and re-created my client's iOS Distribution Certificate - does this mean I can never update my client's existing app?

    - by Schnapple
    Here is the story so far: A client hired us to do an iPhone app for them. This client had never done an iPhone app before and as part of the arrangement we handled all aspects for them, including app store submission, and we handle some level of future development (new features, bug/security fixes, etc.) We created a Distribution certificate and key pair on the client's behalf We developed the app, published it to the App Store without incident Some time later the client hired a second developer to do a different app for them This second developer, it appears, has revoked the existing Distribution certificate and created a new one with a new key pair on their system This second developer shared the new Distribution certificate and key pair with us for future reference. Due to user error, this new certificate and key pair has now been imported onto the Macintosh where the original certificate and key pair for the original app we developed were created and the originals were not backed up. So we have App #1 on the App Store with Distribution certificate/key pair #1 App #2 either on the App Store or soon to be using Distribution certificate/key pair #2 Distribution certificate/key pair #1 appears to be lost now So my question is: if we ever need to update App #1, will we be able to, using Distribution certificate/key pair #2? Or will we have to upload it as a new app?

  • Android&ndash;Finding your SDK debug certificate MD5 fingerprint using Keytool

    - by Bill Osuch
    I recently upgraded to a new development machine, which means the certificate used to sign my applications during debug changed. Under most circumstances you’ll never notice a difference, but if you’re developing apps using Google’s Maps API you’ll find that your old API key no longer works with the new certificate fingerprint. Google's instructions walk you through retrieving the MD5 fingerprint of your SDK debug certificate - the certificate that you’re probably signing your apps with before publishing, but it doesn't talk much about the Keytool command. The thing to remember is that Keytool is part of Java, not the Android SDK, so you'll never find it searching through your Android and Eclipse directories. Mine is located in C:\Program Files\Java\jdk1.7.0_02\bin so you should find yours somewhere similar. From a command prompt, navigate to this directory and type: keytool -v -list -keystore "C:/Documents and Settings/<user name>/.android/debug.keystore" That’s assuming the path to your debug certificate is in the typical location. If this doesn’t work, you can find out where it’s located in Eclipse by clicking Window –> Preferences –> Android –> Build. There's no need to use the additional commands shown on Google's page. You'll be prompted for a password, just hit enter. The last line shown, Certificate fingerprint, is the key you'll give Google to generate your new Maps API key. Technorati Tags: Android Mapping

  • Replace CAPICOM with .NET, validate certificate

    - by Zaky
    Hi My component is responsible for downloading files from the server. As part of file validation I have used CAPICOM (SignedCode object) to validate if a certificate contains a specific string and call to Validate method of the SignedCode object. In case the file contains certificate without a requested string in the name, user was prompted if he trust this file. Since CAPICOM going to be deprecated by Microsoft, I need to implement these logic using .NET libraries. How I can get the same functionality using .NET libraries? Is there any example on the web? Thanks Zaky

  • How to digitally sign a message with M2Crypto using the keys within a DER format certificate

    - by Pablo Santos
    Hi everyone. I am working on a project to implement digital signatures of outgoing messages and decided to use M2Crypto for that. I have a certificate (in DER format) from which I extract the keys to sign the message. For some reason I keep getting an ugly segmentation fault error when I call the "sign_update" method. Given the previous examples I have read here, I am clearly missing something. Here is the example I am working on: from M2Crypto.X509 import * cert = load_cert( 'certificate.cer', format=0 ) Pub_key = cert.get_pubkey() Pub_key.reset_context(md='sha1') Pub_key.sign_init() Pub_key.sign_update( "This should be good." ) print Pub_key.sign_final() Thanks in advance for the help, Pablo
