[−][src]Struct secp256k1::Message

pub struct Message(_);

A (hashed) message input to an ECDSA signature

Methods

`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

`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.

Trait Implementations

`impl<T: ThirtyTwoByteHash> From<T> for Message`[src]

`fn from(t: T) -> Message`[src]

Converts a 32-byte hash directly to a message without error paths

`impl AsRef<[u8; 32]> for Message`

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

Gets a reference to the underlying array
