Dear DragonFlyBSD bugs,
I just learned this morning that NIST has completed their competition for
the new SHA3
cryptographic hash algorithm:
I would recommend that DragonFlyBSD consider deprecating SHA2 for password
hashes, and adopting the new SHA3 algorithm/standard (since SHA1 has been
broken and SHA2 is very similar to SHA1; but note that I bbelieve SHA2 is
Another reason why:
Go to www.slashdot.org and search for "openwall" or "John the Ripper" to
see article on:
"John the Ripper Cracks Slow Hashes On
Basically, even SHA512 was considered problematic in the above article
on cracking password hashes (presumably by brute force).

SHA3 is actually a faster hash function than the SHA2 algorithms, making it less secure in the face of brute force attacks. We won't be changing our hash function until there is a compelling reason to do so, which I do not believe you have provided. Please follow-up if you can provide more compelling evidence that our existing hash (and Linux's, since we use their code) is broken or weak. Until such time, I am closing this.
