Que tal ajudar a dificultar para a NSA espionar você?

Aparentemente, o programa de criptografia PGP é uma das poucas coisas que a NSA ainda não quebrou. Como o programa é desenvolvido por uma fundação sem fins lucrativos, que tal ajudar a dificultar para a NSA espionar você, fazendo uma doação para o desenvolvimento e reforço do GnuPGP?

É fácil, rápido, barato (dá para doar a partir 5 doláres): https://www.gnupg.org/donate/

gpg exe in c sharp .net program

So, I have to get some files encrypted here at work. We are using a version of pgp in our legacy programs, but its so old, I didn't want to use that for the new stuff. Plus I was having a hard time getting it to work period. Apparently there were some licensing issues and stuff and it was so old, we couldn't fix them without upgrading pgp, which costs money. I ended up giving gpg a try, and after some fanagling back and forth with the client, we got it working in theory (In theory meaning I was able to do command line stuff to encrypt and decrypt the files manually).

Next step is actually adding that functionality into the program that builds the file. I can then move the encrypted files into the proper folder and then the client can pick them up. Kind of old school; it would be better if we could use web services or something, but oh well. Anyway, I couldn't fund too much help with how to encrypt the files using gpg2 in c sharp .net. So I've added this entry to try to be helpful, even if its just my future self when I need to remember what I did.

//gpg2exe is the location of the gpg2.exe

//gpgUser is the key to encrypt with static void encryptFile(string filename) {    try {     System.Diagnostics.Process proc = new System.Diagnostics.Process();     String FullGpgCmd = "\"" + gpg2exe + "\" -r " + gpgUser + " -o \"" + filename + ".pgp\" -e \"" + filename + "\"";   proc.EnableRaisingEvents = false;   proc.StartInfo.FileName = "cmd.exe";   proc.StartInfo.RedirectStandardOutput = true;   proc.StartInfo.RedirectStandardInput = true;   proc.StartInfo.UseShellExecute = false;   proc.Start();   proc.StandardInput.WriteLine(FullGpgCmd);   proc.StandardInput.Flush();   proc.StandardInput.Close();   string cmdOutput = "";   while (!proc.HasExited) {     cmdOutput += proc.StandardOutput.ReadToEnd();   }   LogWriter(cmdOutput);   } catch (Exception ex) {     LogWriter(ex.ToString());   } }

This code basically passes the gpg2 command line to cmd.exe in the StandardInput function, and then reads the output. Pretty simple little function, but it could easily be converted to a function to decrypt a file as well.
