Struct secp256k1::Message[][src]

pub struct Message(_);

A (hashed) message input to an ECDSA signature

Implementations

impl Message[src]

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

Converts the object to a raw pointer for FFI interfacing

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

Converts the object to a mutable raw pointer for FFI interfacing

pub fn as_ref(&self) -> &[u8; 32][src]

Gets a reference to the underlying array

pub fn len(&self) -> usize[src]

Returns the length of the object as an array

pub fn is_empty(&self) -> bool[src]

Returns whether the object as an array is empty

impl Message[src]

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

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.
