John, I belive RSA is what your looking for. The basic idea is use the public key to encrypt the private key to decrypt. You can get the RSA class to export the key pair without the private key. Hope this helps ~Nick

Mike, I am aware of how the SSL protocal works. What I am looking for is if someone on has implemented just the Handsake or X509 Certificate exhange portion of the SSL protocal. As the title of this topic suggets. ~Nick

led mike, The public key exchange for SSL is done before the SSL connection is established. I belive this is how the protocal works (Maybe I'm wrong). That is the only portion of the SSL protocal that I am looking to implement. I not really interested in secure communication or ecrypted sockets. I just need the server to transfer me its SSL cert. ~Nick

I know. I have given up hope. I think I am going to the route of setting up an SSLSocket just to get the certificate information from the web server. This seems like a waste of resources to me. ~Nick

Does any one know how to get a remote web server to transfer its Certificate (X509Certifcate) to the local machine using Sockets? I need the public key from a given web server.

led mike, Thank for the information but I am not using sockets or streams. I have a set of files that are digitally signed and I want to make sure their signatures are valid. After getting the files and the digital signatures I need the URL's public key to validate the Signatures. Using Fiddler I noticed the following response on a 443 connect. However, I am not sure how this would translate to x509 certificate in C# code. ~Nick HTTP/1.1 200 Connection Established This is a HTTPS CONNECT Tunnel. Secure traffic flows through this connection.

That namespace is used for code access security. I am interested in Public Key Encryption. I am look for a way to contact a web server and have it transmit me its public key. ~Nick

Forever Developing

Does any know of a way in C# to contact a web server and get the public SSL certificate information? I know all of this is handled by web service calls over https but I need the certificate to do some offline processing outside of webservices. Any help would be greatly appreciated. ~Nick

You could use a simple xor on the password. I think the standard way is to use a MD5 hash or SHA hash. You hash the user password and store the hash in the registry. After you get the plain text password from the user you then hash the password and then compare the hash value to the hash value stored in the registry. This way even if the registry is compromised the password is not stored in the clear. Forever Developing

Not sure why this is but I found a solution to you problem For i = 0 To ds.Tables(0).PrimaryKey.GetUpperBound(0) ComboBox1.Items.Add(ds.Tables(0).PrimaryKey(i).ColumnName()) Next it seems that when filling the schema you cannot refer to the table by its name but only by index number or the value "Table" Forever Developing

What you could do is make a panel for each unqiue ui view. When the tree view node is clicked you remove the old panel and add the new panel via the controls collection on the form. Forever Developing

your problem is that you are creating a new instance of form1. You need to pass in the existing instance of form1 transfertext to take the existing instance public static string transfertext(System.Windows.Forms.Form x) { return x.txtFromSecondClass.Text; } usage string value = SecondClass.transfertext(this); best of luck Forever Developing
