[−][src]Struct secp256k1::schnorrsig::PublicKey
A Schnorr public key, used for verification of Schnorr signatures
Implementations
impl PublicKey
[src]
pub fn as_ptr(&self) -> *const XOnlyPublicKey
[src]
Obtains a raw const pointer suitable for use with FFI functions
pub fn as_mut_ptr(&mut self) -> *mut XOnlyPublicKey
[src]
Obtains a raw mutable pointer suitable for use with FFI functions
pub fn from_keypair<C: Signing>(
secp: &Secp256k1<C>,
keypair: &KeyPair
) -> PublicKey
[src]
secp: &Secp256k1<C>,
keypair: &KeyPair
) -> PublicKey
Creates a new Schnorr public key from a Schnorr key pair
pub fn from_slice(data: &[u8]) -> Result<PublicKey, Error>
[src]
Creates a Schnorr public key directly from a slice
pub fn serialize(&self) -> [u8; 32]
[src]
Serialize the key as a byte-encoded pair of values. In compressed form the y-coordinate is represented by only a single bit, as x determines it up to one bit.
pub fn tweak_add_assign<V: Verification>(
&mut self,
secp: &Secp256k1<V>,
tweak: &[u8]
) -> Result<bool, Error>
[src]
&mut self,
secp: &Secp256k1<V>,
tweak: &[u8]
) -> Result<bool, Error>
Tweak an x-only PublicKey by adding the generator multiplied with the given tweak to it.
Returns a boolean representing the parity of the tweaked key, which can be provided to
tweak_add_check
which can be used to verify a tweak more efficiently than regenerating
it and checking equality. Will return an error if the resulting key would be invalid or
if the tweak was not a 32-byte length slice.
pub fn tweak_add_check<V: Verification>(
&self,
secp: &Secp256k1<V>,
tweaked_key: &Self,
tweaked_parity: bool,
tweak: [u8; 32]
) -> bool
[src]
&self,
secp: &Secp256k1<V>,
tweaked_key: &Self,
tweaked_parity: bool,
tweak: [u8; 32]
) -> bool
Verify that a tweak produced by tweak_add_assign
was computed correctly
Should be called on the original untweaked key. Takes the tweaked key and
output parity from tweak_add_assign
as input.
Currently this is not much more efficient than just recomputing the tweak and checking equality. However, in future this API will support batch verification, which is significantly faster, so it is wise to design protocols with this in mind.
