Struct VerificationMethod 

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

A DID document verification method entry.

Fields

id: String

method_type: String

controller: String

public_key_jwk: Option<Value>

JWK public key representation.

public_key_multibase: Option<String>

Multibase-encoded public key (z prefix = base58btc + multicodec).

Implementations

impl VerificationMethod

pub fn ed25519_public_key_bytes(&self) -> Result<[u8; 32], AcdpError>

Extract the raw 32-byte Ed25519 public key.

Supports both publicKeyJwk (OKP / Ed25519) and publicKeyMultibase (base58btc, multicodec 0xed01 prefix).

pub fn ecdsa_p256_public_key_sec1(&self) -> Result<Vec<u8>, AcdpError>

Extract the SEC1-uncompressed P-256 public key (65 bytes starting with 0x04).

pub fn declared_algorithm(&self) -> Option<&'static str>

Best-effort algorithm declaration derived from the verification method’s type and (when relevant) publicKeyJwk parameters.

Returns the canonical lowercase algorithm string compatible with signature.algorithm (e.g. "ed25519", "ecdsa-p256"), or None for verification methods whose declared algorithm cannot be inferred from type alone.

Used by the high-level Verifier::verify_body to detect algorithm-downgrade attacks per RFC-ACDP-0008 §3.9.
