Subject: Re: QNX Neutrino 6.6.0 password hashes
Hmm, it looks to me like QNX sha512 is broken. Look at this newer page
https://moar.so/tmp/qnx_sha512_broken.txt
So, the first 11 iterations (salt + 12 words) works. The total length of
the string is 112 bytes. 112 bytes 'should' be the first hash which
requires 2 limbs of sha512. It does work, but when another 'password' is
appended (now 120 bytes), the hash returned is no longer correct.
To me, this appears to be a broken core crypto sha512 function within QNX.
