thank you for your suggestion. I agree with you. cracklib is useful to check
password. I only give a example to set password, not force use this rule.
I think password scheme should be more discussion.
I refer to linux password policy. The Linux password rule is configurable.
this is general rule. if you want to set a strength password, you can
use pam_cracklib module.
so we can also config password policy. someone who don't need
a strength password, they can set general rule in keystone.conf.
someone who need strength password, they can load cracklib(or others)
and check password, and password rule can be set by administor.
this is only my idea, can you give me more suggestion?thanks!

If you want to check for password complexity, do it the correct way. I'm
used to *always* use a password generator that uses only lower case, and
removes chars that can be confused with one another, so that you don't
have l and 1, or O and 0 in my passwords. Yet, they are high entropy and
long. If you just force me to add upper+lower case and add symbols, then
you are just annoying me even with my very good passwords.

Please use a password entropy function. Something like this:
