Struct Params 

pub struct Params { /* private fields */ }

The Scrypt parameter values.

Implementations

impl Params

pub const RECOMMENDED_LOG_N: u8 = 17

Recommended log₂ of the Scrypt parameter N: CPU/memory cost.

pub const RECOMMENDED_R: u32 = 8

Recommended Scrypt parameter r: block size.

pub const RECOMMENDED_P: u32 = 1

Recommended Scrypt parameter p: parallelism.

pub const RECOMMENDED_LEN: usize = 32

Recommended Scrypt parameter Key length.

pub const RECOMMENDED: Self

Recommended values according to the OWASP cheat sheet.

• log_n = 17 (n = 131072)
• r = 8
• p = 1

pub fn new(log_n: u8, r: u32, p: u32) -> Result<Params, InvalidParams>

Create a new instance of Params.

Arguments

• log_n - The log₂ of the Scrypt parameter N
• r - The Scrypt parameter r
• p - The Scrypt parameter p

Conditions

• log_n must be less than 64
• r must be greater than 0 and less than or equal to 4294967295
• p must be greater than 0 and less than 4294967295

Errors

Returns InvalidParams if one of the parameters is incorrect.

pub const fn recommended() -> Params

👎Deprecated since 0.12.0:

use Params::RECOMMENDED instead

Deprecated: recommended values according to the OWASP cheat sheet.

pub const fn log_n(&self) -> u8

log₂ of the Scrypt parameter N, the work factor.

Memory and CPU usage scale linearly with N. If you need N, use Params::n instead.

pub const fn n(&self) -> u64

N parameter: the work factor.

This method returns 2 to the power of Params::log_n. Memory and CPU usage scale linearly with N.

pub const fn r(&self) -> u32

r parameter: resource usage.

scrypt iterates 2*r times. Memory and CPU time scale linearly with this parameter.

pub const fn p(&self) -> u32

p parameter: parallelization.
