Hi

It appears that a wrong DOM element was used to check the EncryptedKey element which is actually a sibling of EncryptedData, not a child. I know Colm has very extensively tested it against various IDPs but I believe none of them were encrypting the SAMLP responses.

I've committed a possible fix. Can you please retry the snapshot ?

Cheers, Sergey
