Subject: Re: [PHC] pufferfish

Pufferfish has a minor bug in api.c.  I'm not 100% I got the fix
right, but I am 100% sure this is a bug.  On line 135, memmove is
calling strlen(hash) to determine how much data to copy.  It seems
like it should use strlen instead, assuming Pufferfish supports
variable out length.  Here's the diff after I made this change:
