Groovy: evnark 0.4 Released

Enough has changed that a new version 0.4 release was warranted.  A tool without any real purpose, evnark is a script that parses SSL certificates and reports whether the certificate enabling SSL/TLS encryption on a site is an extended validation one or not.  Another nice thing about evnark is that it is turning out to have quite a comprehensive list of EV certificate policy IDs, which is useful if you want to build something like this on your own.

Changes in this version include:

  1. The addition of two StartCom/StartSSL Certificate Policy IDs.
  2. Added CNNIC (Thanks, Opera!) EV Certificate Policy ID.  (Note:  Although the certificate policy ID has been added, my US English version of OSX Java and most Browsers do not recognize CNNIC as a trusted CA.)  
  3. Modification of those CA keys in the hashmap to account for those cases where some CAs have multiple EV Certificate Policy IDs (like GoDaddy, Comodo, Izenpe, StartCom, DigiCert, etc)  Some of these entries are not very descriptive yet--I assume that they exist to account for different Registration Authorities authorized on behalf of the CA to resell SSL certificates.

Source is below or you can download it (evnark-v0.4.tar.gz or evnark-v0.4.zip) if you don't feel like copying and pasting right now:

#!/usr/bin/env groovy
// usage: 'evnark [-h/--host "hostname"] [-p/--port "port"]'
//
// v0.2 
//   + Adds hostname lookup exception handling
//   + Adds connection timeout exception handling
//   + Modified the output so that it will now state
//     whether or not an EV cert was found.
//
// v0.3
//   + changed display so that successes are now
//     displayed with a green bar (snark)
// v0.3.5
//   + Added TrustCenter aka TC TrustCenter
//   + Added Certum
//   + Added KEYNECTIS
//   + Added additional ev policy id's for GoDaddy, Digicert, Izenpe
// v0.4
//   + Small code cleanup
//   + Added Two Additional StartCom Ltd EV Policy IDs
//   + Added CNNIC EV Policy ID (thanks opera!)
//   + Modifed CA Keys to make them unique to support
//     those cases where there is more than one 
//     certificate policy id getting set.
