If I were going to switch to x86_64 cpu, which I will probably do in the next few years, x32 would certainly be appealing. Not decided for sure, but it seems very nice to get all the important benefits of a 64-bit cpu with none of the bloat. I think this sounds appealing to a big part of musl's target userbase too... > >> Something other than standard crypt (isn't that DES, which can be > >> cracked in a day on the right machine?) would be one of the more > >> interesting ones from my perspective.

Is busybox the only login we want to support? No, and in fact login is utterly useless. It never gets used unless you're logging in at the physical console, or with some horribly insecure legacy protocol like telnet... > 2. Is login (or similar) the only place crypt is used?

Sadly crypto folks seem to love giant bloated tables... Rich
