Real-time entropy estimate, common pattern checks, and crack-time ranges.
Great for demos, security awareness, and explaining best practices.

Note: Crack-time depends heavily on hashing algorithm + attacker hardware. This uses a conservative
“online-ish” and a faster “offline-ish” guess to show ranges.
What I’m checking
Length + character diversity
Repeats (aaaa, 121212)
Simple sequences (abcd, 1234)
Common passwords (small demo list)
Common words / patterns (admin, password, qwerty, years)

Use this slider to demonstrate why strong hashing + MFA matters.
