Struct Argon2 

pub struct Argon2 { /* private fields */ }

Derives a key using Argon2id (V2, the default).

Implementations

impl Argon2

pub fn new() -> Self

Creates an Argon2 key derivation object with default parameters.

pub fn with_params(params: Argon2Parameters) -> Self

Creates an Argon2 key derivation object with custom Argon2Parameters. The caller is responsible for managing the salt (use params.set_salt() if needed).

pub fn parameters(self) -> DerivationParameters

Returns a DerivationParameters capturing the current Argon2 settings. Useful for passing custom parameters to crate::password_hash::hash_password_with_parameters.

pub fn derive(&self, key: &[u8]) -> Result<(SecretKey, DerivationParameters)>

Derives the key using the configured Argon2 parameters. The salt is embedded in Argon2Parameters (generated at construction time when using new()).

Trait Implementations

impl Default for Argon2

fn default() -> Self

Returns the “default value” for a type.
