Subject: Re: formats failing test on big-endian
If this part of the self test is not done:
format.c
+ lengthcheck = 2;
if (lengthcheck == 0 && max == 1) {
lengthcheck = 2;
then dyna_17 works on BE system. I am not sure the reason why, but something is certainly not right. I will keep looking. I know the above 'fix' is not right. But it does show the format is working. It must be something like clear_keys not being properly used for phpass, or something like that. phpass within dyna IS a 'special' format, so there may be newer features that are not properly set.
Kinda hard right now for me to code much. I cut about 3mm of the tip of my middle finger last night. Kinda hard to type right now, lol.
