Struct secp256k1::Message

[+] Show declaration

pub struct Message(_);

[−] Expand description

A (hashed) message input to an ECDSA signature

Implementations

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 as_ref(&self) -> &[u8; 32][−]

Gets a reference to the underlying array

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

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.
