Struct secp256k1::Message [−][src]
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.
