Struct mpc_engine::primitives::commitment::Commitment

pub struct Commitment { /* private fields */ }

A Commitment to some value.

Implementations

impl Commitment

pub fn new( value: &[u8], domain_separator: &[u8], entropy: &mut Randomness ) -> (Self, Opening)

Commit to a value.

Given input value value, samples a random bitstring r of length STATISTICAL_SECURITY and returns a domain separated commitment H(value||r) as well as the corresponding opening.

pub fn open(&self, opening: &Opening) -> Result<Vec<u8>, Error>

Open the commitment, returning the committed value, if successful.

pub fn as_bytes(&self) -> Vec<u8>

Serialize a commitment to a byte vector.

The serialization format is commitment || len(dst) || dst_bytes, where the length is represented as big-endian byte arrays.

pub fn from_bytes(bytes: &[u8]) -> Result<(Self, Vec<u8>), Error>

Deserialize a commitment from a serialization created using Commitment::as_bytes.

Trait Implementations

impl Clone for Commitment

fn clone(&self) -> Commitment

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Commitment

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
