Struct Ed25519Signature 

pub struct Ed25519Signature { /* private fields */ }

Available on crate feature ed25519 only.

An Ed25519 signature.

Implementations

impl Ed25519Signature

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

Creates a signature from raw bytes.

Only the length is validated here. ed25519-dalek 2.x parses the 64 bytes into an (R, s) pair without checking that they form a cryptographically valid signature; whether the signature actually verifies against a given key and message is determined later at verification time (see Ed25519PublicKey::verify).

Errors

Returns AptosError::InvalidSignature if the byte slice length is not exactly 64 bytes.

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

Creates a signature from a hex string.

Errors

Returns AptosError::Hex if the hex string is invalid. Returns AptosError::InvalidSignature if the decoded bytes are not exactly 64 bytes. (As with Self::from_bytes, only the length is validated; cryptographic validity is checked at verification time.)

pub fn to_bytes(&self) -> [u8; 64]

Returns the signature as bytes.

pub fn to_hex(&self) -> String

Returns the signature as a hex string.
