The first two need the '$' escaped just like the third:
time perl -e '$p = "{ssha512}04\$................"; print crypt("", $p), "\n"; for ($n = 0; $n < 100000; $n++) { $c = crypt($n, $p); print "$n $c\n" if ($c =~ /\.\.\.[^\$]*$/); }'
time perl -e '$p = "{ssha512}06\$................"; print crypt("", $p), "\n"; for ($n = 0; $n < 100000; $n++) { $c = crypt($n, $p); print "$n $c\n" if ($c =~ /\.\.\.[^\$]*$/); }'
