Struct AlgorithmIdentifier 

pub struct AlgorithmIdentifier {
    pub algorithm: ObjectIdentifier,
    pub parameters: Option<Any>,
}

Algorithm identifier with optional parameters

Fields

algorithm: ObjectIdentifier

Algorithm OID

parameters: Option<Any>

Optional parameters (usually NULL for hash algorithms)

Implementations

impl AlgorithmIdentifier

pub fn sha256() -> Self

Create a SHA-256 algorithm identifier

pub fn sha384() -> Self

Create a SHA-384 algorithm identifier

pub fn sha512() -> Self

Create a SHA-512 algorithm identifier

pub fn to_hash_algorithm(&self) -> Option<HashAlgorithm>

Try to convert to a HashAlgorithm enum

Trait Implementations

impl Clone for AlgorithmIdentifier

fn clone(&self) -> AlgorithmIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlgorithmIdentifier

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

Formats the value using the given formatter.

impl<'__der_lifetime> DecodeValue<'__der_lifetime> for AlgorithmIdentifier

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

Attempt to decode this message using the provided Reader.

impl<'__der_lifetime> EncodeValue for AlgorithmIdentifier

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 From<HashAlgorithm> for AlgorithmIdentifier

fn from(algo: HashAlgorithm) -> Self

Converts to this type from the input type.

impl PartialEq for AlgorithmIdentifier

fn eq(&self, other: &AlgorithmIdentifier) -> 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.
