Crypt Van Impl

A comparison framework for cryptography implementations in various languages

First target

AES-GCM 256bit key with AAD and tag checking.

running

npm update
npm test <number of iterations>

If there is any discrepancy found between the libraries in use it will report the inputs that triggered that so you can investigate!

To add your library to the framework

1. Create a Node.js wrapper (async or sync) for your the algorithm spec above The wrapper module needs to expose a single function

   /*
    * This function runs your crypto lib from the shell.
    * See the file /python/Cryptography/cryptography.js in this repo for an example.
    */
   function anyNameYouLike(plaintext,iv,additionalAuthenticatedData,key){
     // ... magic happens ...
     
     returns ciphertext+tag // some implementations return them separate others its one combined result.
   }
   
   module.exports = anyNameYouLike     
   

2. Add a reference to your script to index.js with an appropriate name. e.g. encryptRb, encryptGo, encryptPy.

   Then ensure it's called in the async while loop and that the result is passed with the others to the compare function.
