i'm trying to access nonce, cnonce and response params inside auth digest header

but i'm failing miserably. any suggestions i can do this in the script ? 

tried to use @hf_value2.authorization.nonce but it returns the full header (maybe i didn't understood how it works?)

so i was thinking, if there isn't an easy way to get this, i could extend the pv module to add

$an, $acn, $ar (or better names, suggestion welcomed)  to get these values.

thoughts ?
