Struct bitcoin::util::misc::MessageSignature

pub struct MessageSignature {
    pub signature: RecoverableSignature,
    pub compressed: bool,
}

A signature on a Bitcoin Signed Message.

In order to use the to_base64 and from_base64 methods, as well as the fmt::Display and str::FromStr implementations, the base64 feature must be enabled.

Fields

signature: RecoverableSignature

The inner recoverable signature.

compressed: bool

Whether or not this signature was created with a compressed key.

Methods

impl MessageSignature

pub fn new(
    signature: RecoverableSignature,
    compressed: bool
) -> MessageSignature

Create a new [MessageSignature].

pub fn serialize(&self) -> [u8; 65]

Serialize to bytes.

pub fn from_slice(
    bytes: &[u8]
) -> Result<MessageSignature, MessageSignatureError>

Create from a byte slice.

pub fn recover_pubkey<C: Verification>(
    &self,
    secp_ctx: &Secp256k1<C>,
    msg_hash: Hash
) -> Result<PublicKey, Error>

Attempt to recover a public key from the signature and the signed message.

To get the message hash from a message, use [signed_msg_hash].

pub fn is_signed_by_address<C: Verification>(
    &self,
    secp_ctx: &Secp256k1<C>,
    address: &Address,
    msg_hash: Hash
) -> Result<bool, Error>

Verify that the signature signs the message and was signed by the given address.

To get the message hash from a message, use [signed_msg_hash].
