Stefano Bagnara commented on JDKIM-20:
--------------------------------------

I added a catch for the IllegalArgumentException by throwing a PermError with a 
meaningful error. Added a sample synthetical message to the test suite (the 
issue was with unencoded "=" in the value of "i=" parameter).

Also I verified an IllegalStateException while parsing the remote Public Key. I 
added a similar try/catch to the signatureVerify method, as you suggested.

> when calling validate I am seeing IllegalStateExceptions and 
> IllegalArgumentException. 
> It looks like we just need to catch these exceptions in the DKIMVerifier.java
> more specifically, in the verify method we need to add this around line 270 :
>                     } catch (IllegalArgumentException e) {
>                         throw new PermFailException(e.getMessage());
> and we should also add this in the signatureVerify method:
>         try {
>           signature.initVerify(key.getPublicKey());
>         } catch (IllegalStateException e) {
>             throw new PermFailException(e.getMessage());
>         }
