}

Fields

salt: &'a [u8]

scrypt salt

cost_parameter: u64

CPU/Memory cost parameter N.

block_size: u16

Block size parameter r.

parallelization: u16

Parallelization parameter p.

key_length: Option<u16>

PBKDF2 output length

Implementations

impl<'a> ScryptParams<'a>

pub fn from_params_and_salt(params: Params, salt: &'a [u8]) -> Result<Self>

Get the ScryptParams for the provided upstream scrypt::Params and a provided salt string.

Trait Implementations

impl<'a> Clone for ScryptParams<'a>

fn clone(&self) -> ScryptParams<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ScryptParams<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> DecodeValue<'a> for ScryptParams<'a>

fn decode_value<R: Reader<'a>>(reader: &mut R, header: Header) -> Result<Self>

Attempt to decode this message using the provided Reader.

impl EncodeValue for ScryptParams<'_>

fn value_len(&self) -> Result<Length>

Compute the length of this value (sans [Tag]+Length header) when encoded as ASN.1 DER.

fn encode_value(&self, writer: &mut impl Writer) -> Result<()>

Encode value (sans [Tag]+Length header) as ASN.1 DER using the provided Writer.

fn header(&self) -> Result<Header, Error>

where Self: Tagged,

Get the Header used to encode this value.

impl<'a> From<ScryptParams<'a>> for Kdf<'a>

fn from(params: ScryptParams<'a>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for ScryptParams<'a>

fn eq(&self, other: &ScryptParams<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
