This is how my BillingReceiver looks like:public class BillingReceiver ex

  signature certificates integrity timestamping
  I have a PDF document intended for long-term (many years, maybe decades) archival which I would like to digitally sign with my personal certificate to ensure its integrity.As far as I understand, I need to timestamp the signature in order to ensure it remains valid even after certificate expiration.Let’s say I use a trustworthy TSA. From what I understand they sign the timestamp with they own signature.Now, let’s suppose the original TSA bankrupts or is compromised and its certificates revoked.

  gnupg signature
  I was trying to install the newest version of libpcap (as the version in the repositories doesn’t seem current) and ran into the following problem. I copied the tcpdump-workers.asc text from the tcpdump website (which hosts libpcap as well) and imported the key to my keyring using gpg –import tcpdump-workers.asc. That when all well and fine but when I tried to verify the libpcap-1.4.0.tar.gz file against the key with gpg –verify, I ended up getting the message that unexpected data. was found

  c++ signature
  Im trying to get the engine version of a game from a global pointer, but I am fairly new to this. Here is a very small example I found…http://ampaste.net/mb42243And this is the disassembly for what I am trying to get, the pointer (gpszVersionString) is the highlighted line (line 5)http://ampaste.net/m2a8f8887So what I need to find out is basically using the example approach I found to get it, would I need to basically sig out the first part of the function and find the offset to that line?Like

  c++ signature main
  The standard explicitly states that main has two valid (i.e., guaranteed to work) signatures; namely:int main(); int main(int, char*[]);My question is simple, would something like the following be legal?int main(const unsigned int, const char* const* argv);My tests say ‘yes’, but I’m unsure of the answer because am I not overloading main by changing int to unsigned int as well as the non top-level const-ness of argv? If I am, then that’s clearly prohibited.So, are these modifications guaranteed

  c# signature
  I have the following code. Why it always goes to “take(ICollection a)” method? I think the object it self should be LinkedList or HashSet, so it should be calling the other two take method.class Program {static void Main(string[] args){Program p = new Program();ICollection<String>[] ary = { new LinkedList<String>(), new HashSet<String>() };foreach (ICollection<String> a in ary){p.take(a);}for (int i = 0; i < ary.Length; i++){p.take(ary[i]);}}public void take(HashSet&l

  ios xcode signature
  Is it possible to check if iOS application is signed by its developer at applications runtime? I tried to download .ipa of some apps and resigning them with my developer ID and almost all of them worked on my iOS device. But some of them didn’t, so I guess they are somehow checking if signature has changed and forbidding them to run if it is.I know, there is Code Signing Services for OSX, but I haven’t found a way to do this in iOS.Also I have read that after reviewing, apple signs application w

  java main signature main-method
  class NewClass{ public static void main(String a){System.out.print(“Hello”); } }When I’m trying to execute above code, then it shows an error, main method not found. But when I changed public static void main(String a) to public static void main(String… a) or public static void main(String a[]). Then, it works..!! So, My question is how many different ways we can write legal main method signature and what this signature public static void main(String… a) means ?

  rsa public-key signature javascript
  I’m currently working on a secure open source messaging system (https://github.com/DSMNET/DSMNET). Currently I’m using the cryptico.js (https://github.com/wwwtyro/cryptico) library to encrypt all the messages sent. Now to authenticate user’s my server will send a random string and the client will encrypt the string and sign it. The server will check if the signature matches the publickey stored for the user. User’s will generate their public and private key with their password.I would like to

  web-services c#-4.0 int signature webmethod
  I have a c# function with this signature:public XmlNode getName(int a, double b){}problem is that the a variable is not always a valid int (the user can leave it null or a space. In these cases, the function fails (not surprising). How can I validate the int being an int before\in the start of the function?EDIT: the function is a WEBMETHOD in a webservice (asmx file) and that is why the user can type any value into a. The problem is that the webservice crashes when somebody enters a string inste
