I am currently having trouble with verifying the digital signature in a excel file. The digital signature is used to sign the Macro so that it is possible to authenticate and ensure that no one has tamper with the Macro.
Currently, I am able to check that the excel file is digitally signed. However, I can't seem to be able to verify and ensure that the digital signature is authentic. I'm using asp.net 3.5 with vb.net.
I need to validate a digital signature which consists of thumb impression,signature and tokenid which is in pendrive with a columns of a table in sqlserver2008 database. I am using capicom.dll in asp.net 3.5 using c#.
I tried but I am unable to do it.
I am new to digital signature. I have a web application developed in asp.net 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.

View 6 RepliesI 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.
I have never write code like this... so I am trying to explian what problem I meet here..
assuming I have 2 web service
one named WS1 another named WS2
WS1 (send data to WS2) → WS2 then WS2 (receive data from WS1 and do something then return result to WS1)→WS1
if I want to add digital signature between WS1 and WS2 so that WS1 connecting to WS2 , WS2 will recognize who is connecting by digital signature
what do I need if I want to do that? and how to do?
I have asp.net page running under MOSS2007 and there is Access Denied error at signing (signedXml.ComputeSignature()). The code works as normal .net web application but it does not work under MOSS.

View 1 RepliesDoes anyone have any experience with importing meta data files from Ping Identity into an ACS provider?
I'm logged into my Ping Identity admin system, all fine, no problem. Then, when I export the idP file... no digital signature is included within it and thus I cannot import this file into ACS as it complains that there's no signature included.

View 1 RepliesI am doing a project on digital watermarking. This is the process. The user will choose his image file to upload, chooses his image key(either from the visual studio gallery-folder name is Image Key, or he chooses his own from the directory).
He enters a password, and this password will be embedded into the image uploaded.
Next, there is an option to digitally watermark the image (This is where I am having problems - stuck with the codes)
Here is the work so far, and I couldn't get any further.

View 2 RepliesI have an ASP.NET site that uses impersonation. As the impersonated user I use a domain user (not a local machine user). The site is hosted in IIS 6 running on Windows 2003. In IIS 6 for directory security windows authentication is ticked.The site has been running now for about 6 months without any problem. However since about a week back the site has started spuring up really wierd errors. For one, users cannot access the site anymore. When accessing a windows authentication dialog box appears having the user to enter the credentials. However these credentials are not accepted and the standard unauthorized page is displayed
View 7 RepliesI have an ASP.NET application that was working fine on my server up until last night when I installed a bunch of windows updates, now it's throwing this exception : System.Security.SecurityException: Requested registry access is not allowed.Unfortunately there is some things that makes this hard to debug. I added the debug="true" attribute to the web.config file to get the line where the exception is lauched. The line identified in my code is an End If and the code just before seems benign :

Currently, I'm just launching a WebClient to grab the content, rather than through WatiN but that's more untested code in my test suite.
