Struct H0

pub struct H0(/* private fields */);

Initial H value for Argon2

It’s recommended to use only the argon2 function directly, but this allow to disassociate the chosen arguments (password, salt, aad), from the computationally and memory intensive tasks that argon2 go through to derive the final result.

After H0 is computed with one call to blake2, the secret values to the overall argon2 call can be disposed of, allowing for potentially tighter security around the secrets

Implementations

impl H0

pub fn new( params: &Params, password: &[u8], salt: &[u8], key: &[u8], aad: &[u8], tag_length: u32, ) -> Self

Create a new initial hash value for Argon2

The secret material to argon2 (password and key) can be disposed of after this call, and the computation of the value is fast compared to running argon2

Trait Implementations

impl Clone for H0

fn clone(&self) -> H0

Returns a duplicate of the value.

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

Performs copy-assignment from source.
