Struct ScryptHasher 

pub struct ScryptHasher {
    pub params: ScryptParams,
}

A scrypt password hasher that bundles its own cost parameters.

Implements PasswordHash so it can be used polymorphically with crate::verify_password.

Design note — params argument is ignored

The PasswordHash::hash_password trait method accepts a params: &dyn PasswordHashParams argument, but this implementation ignores it and uses self.params instead. Callers that need different scrypt parameters should construct a new ScryptHasher with the desired ScryptParams rather than passing a different PasswordHashParams object.

Fields

params: ScryptParams

Scrypt cost parameters.

Implementations

impl ScryptHasher

pub fn new(params: ScryptParams) -> Result<Self, CryptoError>

Create a new hasher with explicit parameters.

Returns an error if the parameters are out of range.

pub fn new_checked(params: ScryptParams) -> Self

Create a new hasher, panicking if params are invalid.

Prefer ScryptHasher::new in production code.

pub fn interactive() -> Self

Interactive login preset.

pub fn moderate() -> Self

Moderate (balanced) preset.

pub fn sensitive() -> Self

Sensitive (high-security) preset.

Trait Implementations
