Module password 

Password strength analysis and validation.

Provides entropy calculation and feedback to prevent users from undermining Shield’s EXPTIME security with weak passwords.

Example

use shield_core::password::{check_password, StrengthLevel};

let result = check_password("MyP@ssw0rd123!");
println!("Entropy: {:.1} bits", result.entropy);
println!("Level: {:?}", result.level);
println!("Crack time: {}", result.crack_time_display());
