Struct saito_rust::crypto::Message

pub struct Message(_);

A (hashed) message input to an ECDSA signature

Implementations

impl Message

pub fn from_slice(data: &[u8]) -> Result<Message, Error>

If you just want to sign an arbitrary message use Message::from_hashed_data instead.

Converts a MESSAGE_SIZE-byte slice to a message object. WARNING: the slice has to be a cryptographically secure hash of the actual message that’s going to be signed. Otherwise the result of signing isn’t a secure signature.

impl Message

pub fn as_ptr(&self) -> *const u8

Converts the object to a raw pointer for FFI interfacing

pub fn as_mut_ptr(&mut self) -> *mut u8

Converts the object to a mutable raw pointer for FFI interfacing

pub fn len(&self) -> usize

Returns the length of the object as an array

pub fn is_empty(&self) -> bool

Returns whether the object as an array is empty
