I have a signedXML object Dim signedXml As New SignedXml (envelope)I need to set the SigningKey property of this object signedXml.SigningKey..I also have my certificate object Dim cert As X509Certificate = Me.GetX509Certificate...How can I set the SigningKey property of signedXml using my cert.In .NET 2.0 each X509Certificate had a 'Key' property which returned an RSA object, but in 3.5 this property is removed.
View 2 RepliesI am loading a certificate from string like this:
public static void Test()
{
byte[] arrayCertificate;
[Code]....
But this certificate doesn't have a "Subject Unique Identifier" Take a look at this:
[URL] (The part of Structure of a certificate)
And I want to know how can I read that value from my .NET code (I looked that I can get SerialNumber, Thumbprints and others but there is no Subject UID anywhere).
If anyone can share an openssl command to include this UID for the certificate :-) (pfx one)
Greetings, I am trying to install a certificate from a .p12 file into the Local Machine - Personal store and set the permissions for Everyone to full control. I can acheive this manually with mmc on W7 (or mmc + WSE Certificate Tool on XP.) When attempting with the vb.net code below I get no errors but when I try to access the security tab (Manage Private Keys in mmc on W7, or WSE Certificate Tools on XP) I get the error, "No keys found for certificate!"
I am using the following code to install the certificate, which seems to be working. However I am not convinced its placing the private key in the correct place. I have tried two methods for setting permissions on the private key and the second method, which locates the private key file indicates the private key is being stored under usersmy-user-account... Should that be a public account

I went to load an app I was working on before my system died a few days back and I loaded up VB Express 2010 .Net, opened my project and saw this error ...
Error1Unable to find manifest signing certificate in the certificate store.HexHelperProject
If this is related to the Security Certificates stored by XP, then I'm in trouble as they are GONE. Must I start a new project and rebuild this whole app?
I am having an issue getting the below error. This error is in a small mail app using smtpClient. I had this working on this same computer but had to reformat and now I am getting the error.

View 9 RepliesI have been using RSACryptoServiceProvider and was using the template code provided from the MSDN resource page.url...I wanted to encrypt the data on my computer and transfer the data to the FTP server and have it decrypted there. I have the encryption and decryption code but it is in the same program and only work during the instance it is open. The intention is to have a program that will encrypt and send the data to the FTP Server. There will also be a VB Script on the server to decrypt the data and store it in a separate location. How do I get it to store the public key on my computer and the private key on the server? Also, how to I transfer the encrypted data over to the FTP and have it saved there?The purpose of this project is that we have people located over the globe and are sending sensitive information to an FTP server at the home office. My boss has insisted on the data being encrypted before sending anything. But, on the server it will be decrypted so that a select few can go through the information.

We have somewhat bureaucratic way of making new users to our system. I noticed I had to write same info over and over again to different places (such as AD and our databases). So I desided to make a little application that inserts the info to all the right places with one click. Now I can create new user with one form and push of a button except the client certificate. For that I must login to our certserv and fill in a form.
Is there an easy way to make client sertificate request to the certserv so that it would give me the certificate automatically? I tried to google about it and got some info about the system.security.cryptography, but got stuck before getting any near of requesting new certificate.
I am trying to get OpenSSL.net to 1) create a key pair to use for CA signing and 2) create and sign certificates using this CA. I have managed to create an RSA/SHA1 X509CertificateAuthority, and have created a X509Request and keys, but I am running into problems actually signing the request.

View 2 RepliesI try to run my Authenticode signed app on a clean Vista PC (not internet connection available ever). I have a look in Internet Explorer if the root certificate (Trustcenter) is there, and it is not. I get the message that the reference could not be resolved, and when I click file properties and have a look at the certificate, it says "The certificate for the signature could not be confirmed". Is that a normal behaviour? I mean does the computer need to have the root certificate from Trustcenter installed?

Is there a collection or property somewhere to determine the certificate properties that is in used with the current browser?

I have an application that was deployed almost a year ago using clickonce. My Test certificate is about to expire. Seemed to have read somewhere that the problem was fixed in VS 2008. Can someone confirm and tell me if there is something I have to do to keep my users up and running? Also, if I make changes to the application and redeploy after the expire date, is there anything I need to do? I don't know anything about certificates just that I had to create one to use ClickOnce.

View 3 RepliesI have been trying to get a test 'developer use' authenticode certificate working on our server. We dont really want to pay for one until we have tested internally so we are using a test cert generated by tech-pro. So far i have:
- Installed certificate services sucessfully.
- Created a test certificate using tech-pro codesign.
- used signtool.exe wizard to sign the application.
- imported the test certifcate as a server root certificate.
All appears to have gone ok and without error but when i run the exe on a virtual VISTA machine logged onto the domain the program still prompts for the administrator to logon to elevate its priviliges. Is there another step im missing that requires me to specifically register the certificate directly on the virtual machine too? Or something else i need to do on the server to make that certificate valid for our domain?
