Struct BalloonHasher 

pub struct BalloonHasher {
    pub variant: BalloonVariant,
    pub params: BalloonParams,
}

A Balloon password hasher bundling its variant and cost parameters.

Implements PasswordHash so it composes with crate::verify_password.

Design note — params argument is ignored

PasswordHash::hash_password accepts a params: &dyn PasswordHashParams, but this implementation uses self.params instead. The output length is fixed by the variant (32 bytes for SHA-256, 64 for SHA-512); out must match.

Fields

variant: BalloonVariant

Underlying hash variant.

params: BalloonParams

Cost parameters.

Implementations

impl BalloonHasher

pub fn new_sha256(params: BalloonParams) -> BalloonHasher

Create a Balloon-SHA-256 hasher with the given parameters.

pub fn new_sha512(params: BalloonParams) -> BalloonHasher

Create a Balloon-SHA-512 hasher with the given parameters.

pub fn output_len(&self) -> usize

Digest length in bytes for this hasher’s variant.
