Struct PasswordStore 

pub struct PasswordStore { /* private fields */ }

Password store for managing user authentication

Implementations

impl PasswordStore

pub fn new() -> Self

Create a new empty password store

pub fn load_from_file<P: AsRef<Path>>(path: P) -> Result<Self>

Load passwords from a file

File format: username:password (one per line) Password formats supported:

• Argon2 PHC format: username:$argon2id$v=19$m=... (recommended, secure storage)
• Cleartext: username:mysecret (will be hashed with Argon2 on load)
• MD5 for wire protocol: username:{MD5}hash (for PostgreSQL MD5 wire protocol compatibility)

Comments start with # and empty lines are ignored.

Security note: Cleartext passwords will be automatically hashed with Argon2. For PostgreSQL MD5 wire protocol, use {MD5} prefix (less secure storage).

pub fn add_user(&mut self, username: String, password: &str) -> Result<()>

Add a user with a password (will be hashed with Argon2)

pub fn add_user_hashed(&mut self, username: String, password_hash: String)

Add a user with an already-hashed password

pub fn get_password(&self, username: &str) -> Option<&String>

Get the stored password for a user

pub fn verify_cleartext(&self, username: &str, password: &str) -> bool

Verify a cleartext password for a user This works with Argon2 hashes (recommended) but not with {MD5} format

pub fn verify_md5( &self, username: &str, password_hash: &str, salt: &[u8; 4], ) -> bool

Verify an MD5 password for a user PostgreSQL MD5 format: md5(md5(password + username) + salt) This only works if the password is stored in {MD5}cleartext format
