Security :: How To Implement Digital Signature

Aug 12, 2010

I am new to digital signature. I have a web application developed in 3.5. In one of the module of this application I am generating pdf file and storing it on the server. The users must be able to choose a pdf file and digitally sign it with a certificate stored locally (either on their machine or in a smartcard). I do not know whether I should pass pdf file to client place to sign it or I should send Certificate object to the server.

Security :: How To Verify Digital Signature Of JAR/APK

Feb 19, 2010

I posted this previously but it ended up in Languages/C# rather than here. I'm not sure if I chose the wrong forum or the admin moved it. I wanted it in here so I'm re-posting it:

I have an APK file (android application archive, same as JAR file format) that I need to determine whether or not is signed, and if so, extract the certificate info.

The JDK provides a command line tool to do this:

jarsigner -verbose -certs -verify file.apk

I'm trying to determine if there's a way using the Security classes to accomplish the same thing in C# code.

If I'm taking a password on a page, should that page be served via https and exactly how dangerous is it not to? I've tried googling this but every guide just says that ssl certificates "stop hackers seeing sensative data" with no real description of how they would do this or exactly how vulnerable your site is as a result of not having ssl.Could someone summarize how easy it is for someone to steal passwords on non-https pages? Should i even be considering doing a login page without one?

Security :: Get Remote SSL Certificate Information?

Nov 27, 2010

I am looking to get the data from any given domain names SSL certificate. For example I want to put in any website address e.g. "" and my code would firstly check if an SSL certificate exists. If it does then I want it to pull out the Issuer, Subject, Valid From and Valid Until etc. The intention is to create an SSL certificate checker similar to this: [URL]

How can I do this - I have looked up loads of different things such as RequestCertificateValidationCallback and ClientCertificates etc.

would I create a HTTPWebRequest and then somehow request the client certificate and specific elements that way?

Security :: SSL - Programitically Locate SSL Certificate?

Mar 11, 2010

This is my first time stepping into the wonderful world of SSL. I am working on a project which forces the HTTPS protocol/ Url Scheme for certain parts of the site. I mananged to get that working fine.


There is another part of the project where I pull binary image data from a database, and then write/render the image onto the browser window. <b>I found that since I converted the site to SSL, the rendering no longer works</b>. I am now working under the believe that I must open my a System.Net.Security.SSLStream in order to stream the bytes to the Response.

<br/>I'm at the point where I am writing the SSLStream, but there is a major roadblock. I don't know how to
programmatically locate my X509Certificate so that I can authenticate the SSLStream. To make this problem a little more challenging, I am working with a somewhat-unpopular shared hosting provider, who does not give me access to the certificate name - which probably is not a big deal. I am guessing I'm just going about this problem the wrong way. <br/>

Security :: Using A X509 Certificate In A Web-service

Jun 17, 2010

I have a rather strange situation that I am in.

I have to write a web-service that will (among other things) communicate with another web service. When we communicate with that remote web-service we are required to use a certificate that they provided.

I am having a really hard time trying to find any sample code that does this.

I have found code for installing certs when you want to use a browser to communicate, but none when you are using a web-service to web-service and you are required to HAVE the certificate, not requiring the OTHER end to have the certificate.

So far I cannot even find code to allow me to parse throught the cert store. Samples I found online show up as errors in Visual Studio 2005.

Note: This is running one Windows 2000, designed with Visual Studio 2005, 2.0
