Enum Kdf 

#[non_exhaustive]
pub enum Kdf<'a> {
    Pbkdf2(Pbkdf2Params<'a>),
    Scrypt(ScryptParams<'a>),
}

Password-based key derivation function.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Pbkdf2(Pbkdf2Params<'a>)

Password-Based Key Derivation Function 2 (PBKDF2).

Scrypt(ScryptParams<'a>)

scrypt sequential memory-hard password hashing function.

Implementations

impl<'a> Kdf<'a>

pub fn key_length(&self) -> Option<u16>

Get derived key length in bytes, if defined.

pub fn oid(&self) -> ObjectIdentifier

Get the ObjectIdentifier (a.k.a OID) for this algorithm.

pub fn pbkdf2(&self) -> Option<&Pbkdf2Params<'a>>

Get Pbkdf2Params if it is the selected algorithm.

pub fn scrypt(&self) -> Option<&ScryptParams<'a>>

Get ScryptParams if it is the selected algorithm.

pub fn is_pbkdf2(&self) -> bool

Is the selected KDF PBKDF2?

pub fn is_scrypt(&self) -> bool

Is the selected KDF scrypt?

pub fn to_alg_params_invalid(&self) -> Error

Convenience function to turn the OID (see oid) of this Kdf into error case Error::AlgorithmParametersInvalid

Trait Implementations

impl<'a> Clone for Kdf<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Kdf<'a>

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

Formats the value using the given formatter.

impl<'a> DecodeValue<'a> for Kdf<'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 Kdf<'_>

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<Pbkdf2Params<'a>> for Kdf<'a>

fn from(params: Pbkdf2Params<'a>) -> Self

Converts to this type from the input type.

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 Kdf<'a>

fn eq(&self, other: &Kdf<'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.

type Error = Error

The type returned in the event of a conversion error.

fn try_from(alg: AlgorithmIdentifierRef<'a>) -> Result<Self>
