Struct Argon2 

pub struct Argon2<'key> { /* private fields */ }

Argon2 context.

This is the primary type of this crate’s API, and contains the following:

• Argon2 Algorithm variant to be used
• Argon2 Version to be used
• Default set of Params to be used
• (Optional) Secret key a.k.a. “pepper” to be used

Implementations

impl<'key> Argon2<'key>

pub fn new(algorithm: Algorithm, version: Version, params: Params) -> Self

Create a new Argon2 context.

pub fn new_with_secret( secret: &'key [u8], algorithm: Algorithm, version: Version, params: Params, ) -> Result<Self>

Create a new Argon2 context.

pub fn hash_password_into( &self, pwd: &[u8], salt: &[u8], out: &mut [u8], ) -> Result<()>

Available on crate feature alloc only.

Hash a password and associated parameters into the provided output buffer.

pub fn hash_password_into_with_memory( &self, pwd: &[u8], salt: &[u8], out: &mut [u8], memory_blocks: impl AsMut<[Block]>, ) -> Result<()>

Hash a password and associated parameters into the provided output buffer.

This method takes an explicit memory_blocks parameter which allows the caller to provide the backing storage for the algorithm’s state:

• Users with the alloc feature enabled can use Argon2::hash_password_into to have it allocated for them.
• no_std users on “heapless” targets can use an array of the Block type to stack allocate this buffer.

pub fn fill_memory( &self, pwd: &[u8], salt: &[u8], memory_blocks: impl AsMut<[Block]>, ) -> Result<()>

Use a password and associated parameters only to fill the given memory blocks.

This method omits the calculation of a hash and can be used when only the filled memory is required. It is not necessary to call this method before calling any of the hashing functions.

pub const fn params(&self) -> &Params

Get default configured Params.

Trait Implementations

impl<'key> Clone for Argon2<'key>

fn clone(&self) -> Argon2<'key>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Argon2<'_>

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

Formats the value using the given formatter.

impl Default for Argon2<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'key> From<&Params> for Argon2<'key>

fn from(params: &Params) -> Self

Converts to this type from the input type.

impl<'key> From<Params> for Argon2<'key>

fn from(params: Params) -> Self

Converts to this type from the input type.

impl PasswordHasher for Argon2<'_>

Available on crate features alloc and password-hash only.

type Params = Params

Algorithm-specific parameters.

fn hash_password<'a>( &self, password: &[u8], salt: impl Into<Salt<'a>>, ) -> Result<PasswordHash<'a>>

Simple API for computing a PasswordHash from a password and salt value.

fn hash_password_customized<'a>( &self, password: &[u8], alg_id: Option<Ident<'a>>, version: Option<Decimal>, params: Params, salt: impl Into<Salt<'a>>, ) -> Result<PasswordHash<'a>>

Compute a PasswordHash from the provided password using an explicit set of customized algorithm parameters as opposed to the defaults.
