Struct PasscodeKdf 

pub struct PasscodeKdf {
    pub kind: u32,
    pub generation: u32,
    pub memory: u32,
    pub time: u32,
    pub parallelism: u32,
}

Parameters of one passcode wrap.

For Argon2id memory is the memory cost in KiB, time the pass count, and parallelism the lane count; for scrypt they are N, r, and p.

Fields

kind: u32

KDF family: KDF_ARGON2ID or KDF_SCRYPT.

generation: u32

Generation of the wrap; only wraps of the committed generation are live.

memory: u32

Argon2id memory in KiB, or scrypt N.

time: u32

Argon2id passes, or scrypt r.

parallelism: u32

Argon2id lanes, or scrypt p.

Implementations

impl PasscodeKdf

pub fn valid(&self) -> bool

Whether the parameters describe a derivation the KDF accepts.

pub fn cost_within_limits(&self) -> bool

Whether the cost is inside the read caps of crate::kdf; other kinds have no cost and are always within limits.
