}

A COSE signature algorithm, indicating the type of key and hash type that should be used. You shouldn’t need to alter or use this value.

Variants

ES256 = -7

Identifies this key as ECDSA (recommended SECP256R1) with SHA256 hashing

ES384 = -35

Identifies this key as ECDSA (recommended SECP384R1) with SHA384 hashing

ES512 = -36

Identifies this key as ECDSA (recommended SECP521R1) with SHA512 hashing

RS256 = -257

Identifies this key as RS256 aka RSASSA-PKCS1-v1_5 w/ SHA-256

RS384 = -258

Identifies this key as RS384 aka RSASSA-PKCS1-v1_5 w/ SHA-384

RS512 = -259

Identifies this key as RS512 aka RSASSA-PKCS1-v1_5 w/ SHA-512

PS256 = -37

Identifies this key as PS256 aka RSASSA-PSS w/ SHA-256

PS384 = -38

Identifies this key as PS384 aka RSASSA-PSS w/ SHA-384

PS512 = -39

Identifies this key as PS512 aka RSASSA-PSS w/ SHA-512

EDDSA = -8

Identifies this key as EdDSA (likely curve ed25519)

INSECURE_RS1 = -65_535

Identifies this as an INSECURE RS1 aka RSASSA-PKCS1-v1_5 using SHA-1. This is not used by validators, but can exist in some windows hello tpm’s

PinUvProtocol = 4294901762

Identifies this key as the protocol used for PIN/UV Auth Protocol One

This reports as algorithm -25, but it is a lie. Don’t include this in any algorithm lists.

Implementations

impl COSEAlgorithm

pub fn secure_algs() -> Vec<COSEAlgorithm>

Return the set of secure recommended COSEAlgorithm’s

pub fn all_possible_algs() -> Vec<COSEAlgorithm>

Return the set of all possible algorithms that may exist as a COSEAlgorithm

Trait Implementations

impl Clone for COSEAlgorithm

fn clone(&self) -> COSEAlgorithm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for COSEAlgorithm

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for COSEAlgorithm

fn deserialize<__D>( __deserializer: __D, ) -> Result<COSEAlgorithm, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for COSEAlgorithm

fn eq(&self, other: &COSEAlgorithm) -> bool

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

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

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

impl Serialize for COSEAlgorithm

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<i128> for COSEAlgorithm

type Error = ()

The type returned in the event of a conversion error.

fn try_from( i: i128, ) -> Result<COSEAlgorithm, <COSEAlgorithm as TryFrom<i128>>::Error>

Performs the conversion.

impl Copy for COSEAlgorithm

impl Eq for COSEAlgorithm

impl StructuralPartialEq for COSEAlgorithm
