Struct Argon2Params 

pub struct Argon2Params {
    pub memory_kib: u32,
    pub passes: u32,
    pub lanes: u32,
}

Cost parameters.

Fields

memory_kib: u32

Memory in kibibytes.

passes: u32

Number of passes over the memory.

lanes: u32

Degree of parallelism (lanes).

Implementations

impl Argon2Params

pub const RECOMMENDED: Argon2Params

RFC 9106’s first recommendation: 2 GiB, one pass, four lanes.

Use this for offline key derivation where a second of latency and two gibibytes of resident memory are acceptable.

pub const INTERACTIVE: Argon2Params

RFC 9106’s second recommendation: 64 MiB, three passes, four lanes.

For interactive logins, where the 2 GiB option would be a denial of service against your own server.

pub fn validate(&self) -> Result<()>

Check the parameters against RFC 9106’s limits.
