Thank you!

I'd prefer Perl if you can.

Let's hope someone will post the original plist file from a Lion system,
for an unimportant account/password indeed.  Anyone?

Which would be the hardest then?

Meanwhile, here's what I am getting (will be in 1.7.8-jumbo-6):

Benchmarking: Mac OS X 10.7+ salted SHA-512 [64/64]... (8xOMP) DONE
Many salts:     9501K c/s real, 1186K c/s virtual
Only one salt:  5489K c/s real, 684496 c/s virtual

Benchmarking: Mac OS X 10.4 - 10.6 salted SHA-1 [32/64]... (8xOMP) DONE
Many salts:     22629K c/s real, 2825K c/s virtual
Only one salt:  8967K c/s real, 1119K c/s virtual

That's on 2xE5420 2.5 GHz using OpenSSL crypto code.

Non-OpenMP build, same machine (using one CPU core):

Benchmarking: Mac OS X 10.7+ salted SHA-512 [64/64]... DONE
Many salts:     1457K c/s real, 1457K c/s virtual
Only one salt:  1362K c/s real, 1362K c/s virtual

Benchmarking: Mac OS X 10.4 - 10.6 salted SHA-1 [32/64]... DONE
Many salts:     3676K c/s real, 3676K c/s virtual
Only one salt:  3124K c/s real, 3124K c/s virtual

(I optimized the "XSHA" code a bit while I was at it.)
