title: Authenticode or other code signing for Mac and Linux
body: <p>Is there anything similar to Authenticode for Mac and Linux?</p>
  
  <p>If yes, could anyone point to a sample snippet, preferably in C, on how to check that the signature match? </p>
  
  <p>Thank you</p>
  
  <p>EDIT: There is one possible answer to the Mac part in <a href="https://stackoverflow.com/questions/1815506/how-to-obtain-codesigned-application-certificate-info">here</a> but I don't know whether this can be done in plain C.</p>
