Struct VerificationMethod 

pub struct VerificationMethod {
    pub id: String,
    pub typ: String,
    pub controller: String,
    pub public_key_jwk: Option<Map<String, Value>>,
    pub public_key_multibase: Option<String>,
}

A verification method entry in a DID Document.

Per W3C DID Core §5.2, a verification method has an id, type, controller, and one public key representation. The most common types are:

• JsonWebKey2020 + publicKeyJwk
• Ed25519VerificationKey2020 + publicKeyMultibase

Fields

id: String

DID URL identifying this verification method (e.g. did:ndn:…#key-0).

typ: String

Verification method type.

Common values:

• "JsonWebKey2020" — public key as JWK
• "Ed25519VerificationKey2020" — Ed25519 as multibase
• "X25519KeyAgreementKey2020" — X25519 for ECDH key agreement

controller: String

DID of the entity that controls this key.

public_key_jwk: Option<Map<String, Value>>

Public key as a JSON Web Key (for JsonWebKey2020 type).

public_key_multibase: Option<String>

Public key as a multibase-encoded string (for Ed25519VerificationKey2020 and X25519KeyAgreementKey2020 types). The leading character encodes the base: z = base58btc.

Implementations

impl VerificationMethod

pub fn ed25519_jwk( id: impl Into<String>, controller: impl Into<String>, key_bytes: &[u8], ) -> Self

Build a JsonWebKey2020 verification method from raw Ed25519 public key bytes.

pub fn x25519_jwk( id: impl Into<String>, controller: impl Into<String>, key_bytes: &[u8], ) -> Self

Build a X25519KeyAgreementKey2020 verification method from raw X25519 key bytes.

pub fn ed25519_key_bytes(&self) -> Option<[u8; 32]>

Extract the raw Ed25519 public key bytes from a JsonWebKey2020 VM.

pub fn x25519_key_bytes(&self) -> Option<[u8; 32]>

Extract the raw X25519 public key bytes from a JsonWebKey2020 VM.

Trait Implementations

impl Clone for VerificationMethod

fn clone(&self) -> VerificationMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VerificationMethod

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VerificationMethod

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VerificationMethod

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

impl Serialize for VerificationMethod

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
