Implementations

impl VerifyingKey

pub fn to_multibase(&self) -> String

The publicKeyMultibase value for a DID document verification method: base58btc multibase over the multicodec prefix 0xE7 and the 33-byte SEC1 compressed point.

Compression is requested explicitly here because k256 can produce either form and an uncompressed key is not valid in atproto.

pub fn to_did_key(&self) -> String

The did:key URI form: the did:key: prefix plus VerifyingKey::to_multibase.

pub fn from_did_key(did: &str) -> Result<Self, KeyError>

Parses a did:key:z... URI.

jacquard-common decodes bare multibase strings, not URIs, so the prefix is stripped here.

pub fn from_multibase(multibase: &str) -> Result<Self, KeyError>

Parses a bare publicKeyMultibase string.

Rejects any curve other than secp256k1 and any encoding other than the 33-byte compressed point, so that a key which round-trips through this crate is one atproto will accept.

pub fn verify(&self, message: &[u8], sig: &Signature) -> Result<(), KeyError>

Verifies a signature over message.

A high-S signature fails here, because k256 rejects one internally.

pub fn as_k256(&self) -> &VerifyingKey

The underlying k256 key, for callers doing their own point work.

Trait Implementations

impl Clone for VerifyingKey

fn clone(&self) -> VerifyingKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VerifyingKey

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

Formats the value using the given formatter.

impl PartialEq for VerifyingKey

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