Struct secp256k1::key::SecretKey

pub struct SecretKey(_);

Secret 256-bit key used as x in an ECDSA signature

Implementations

impl SecretKey

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 SecretKey

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

Converts a SECRET_KEY_SIZE-byte slice to a secret key

pub fn negate_assign(&mut self)

Negates one secret key.

pub fn add_assign(&mut self, other: &[u8]) -> Result<(), Error>

Adds one secret key to another, modulo the curve order. WIll return an error if the resulting key would be invalid or if the tweak was not a 32-byte length slice.

pub fn mul_assign(&mut self, other: &[u8]) -> Result<(), Error>

Multiplies one secret key by another, modulo the curve order. Will return an error if the resulting key would be invalid or if the tweak was not a 32-byte length slice.
