Struct bdk_chain::bitcoin::secp256k1::Message

pub struct Message(/* private fields */);
Expand description

A (hashed) message input to an ECDSA signature.

Implementations§

§

impl Message

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

👎Deprecated since 0.28.0: use from_digest_slice instead

Creates a Message from a 32 byte slice digest.

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.

pub fn from_digest(digest: [u8; 32]) -> Message

Creates a Message from a digest.

The digest array 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.

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

Creates a Message from a 32 byte slice digest.

The slice has to be 32 bytes long and 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.

§Errors

If digest is not exactly 32 bytes long.
