Implementations

impl PasswordPolicy

pub fn nist_800_63b() -> Self

NIST SP 800-63B compliant policy.

Follows modern NIST guidance: no arbitrary composition rules, focus on length and entropy. Banned password list still applies.

use auth_framework::utils::validation::PasswordPolicy;
let policy = PasswordPolicy::nist_800_63b();
assert_eq!(policy.min_length, 8);
assert!(!policy.require_special);

pub fn high_security() -> Self

High-security policy with strict composition requirements.

Suitable for admin accounts and sensitive systems.

use auth_framework::utils::validation::PasswordPolicy;
let policy = PasswordPolicy::high_security();
assert_eq!(policy.min_length, 12);
assert!(policy.require_special);

pub fn with_banned_words(self, words: &[&str]) -> Self

Add custom banned passwords on top of the existing list.

Words are lowercased before insertion.

pub fn builder() -> PasswordPolicyBuilder

Create a builder starting from the default policy.

Trait Implementations

impl Clone for PasswordPolicy

fn clone(&self) -> PasswordPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PasswordPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PasswordPolicy

fn default() -> Self

Returns the “default value” for a type.
