Struct Bls12381Signature 

pub struct Bls12381Signature { /* private fields */ }

Available on crate feature bls only.

A BLS12-381 signature.

Implementations

impl Bls12381Signature

pub fn from_bytes(bytes: &[u8]) -> AptosResult<Self>

Creates a signature from compressed bytes (96 bytes).

Errors

Returns an error if the bytes length is not 96 bytes or if the signature deserialization fails.

pub fn from_hex(hex_str: &str) -> AptosResult<Self>

Creates a signature from a hex string.

Errors

Returns an error if hex decoding fails or if the resulting bytes are invalid.

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

Returns the signature as compressed bytes (96 bytes).

pub fn to_hex(&self) -> String

Returns the signature as a hex string.

impl Bls12381Signature

pub fn aggregate( signatures: &[&Bls12381Signature], ) -> AptosResult<Bls12381Signature>

Aggregates multiple signatures into a single aggregated signature.

The resulting signature can be verified with Bls12381PublicKey::verify against the aggregate public key (see Bls12381PublicKey::aggregate) when every signer signed the same message.

Note: this SDK does not expose an aggregate-verify API for the case where the signers signed different messages, so only the shared-message aggregation described above is supported here.

Errors

Returns an error if the list of signatures is empty or if aggregation fails.
