Struct AnyPublicKey 

pub struct AnyPublicKey {
    pub variant: AnyPublicKeyVariant,
    pub bytes: Vec<u8>,
}

A public key that can be any supported signature scheme.

Fields

variant: AnyPublicKeyVariant

The signature scheme variant.

bytes: Vec<u8>

The raw public key bytes.

Implementations

impl AnyPublicKey

pub fn new(variant: AnyPublicKeyVariant, bytes: Vec<u8>) -> Self

Creates a new AnyPublicKey.

pub fn ed25519(public_key: &Ed25519PublicKey) -> Self

Available on crate feature ed25519 only.

Creates an Ed25519 public key.

pub fn secp256k1(public_key: &Secp256k1PublicKey) -> Self

Available on crate feature secp256k1 only.

Creates a Secp256k1 public key. Uses uncompressed format (65 bytes) as required by the Aptos protocol.

pub fn secp256r1(public_key: &Secp256r1PublicKey) -> Self

Available on crate feature secp256r1 only.

Creates a Secp256r1 public key. Uses uncompressed format (65 bytes) as required by the Aptos protocol.

pub fn to_bcs_bytes(&self) -> Vec<u8>

Serializes to BCS format: variant_byte || ULEB128(length) || bytes

This is the correct BCS serialization format for AnyPublicKey used in authentication key derivation: SHA3-256(BCS(AnyPublicKey) || scheme_id)

pub fn verify( &self, message: &[u8], signature: &AnySignature, ) -> AptosResult<()>

Verifies a signature against a message.

Errors

This function will return an error if:

• The signature variant doesn’t match the public key variant
• The public key bytes are invalid for the variant
• The signature bytes are invalid for the variant
• Signature verification fails
• Verification is not supported for the variant

Trait Implementations

impl Clone for AnyPublicKey

fn clone(&self) -> AnyPublicKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnyPublicKey

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

Formats the value using the given formatter.

impl Display for AnyPublicKey

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

Formats the value using the given formatter.

impl PartialEq for AnyPublicKey

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