--- Comment #2 from Luca Toscano <toscano.l...@gmail.com> ---
Hi Hanno,

thanks a lot for the report. The following patch seems to work for me:

./support/htdigest poc try elukey

The following line is longer than the maximum allowed (256):
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

I am not familiar with the htdigest.c code so I'll need to take a deeper look.
Will wait for other people's comments too :)

Luca
