Implementations

impl RangeProof

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

Serialize to bytes.

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

Parse from byte slice.

TODO: Rename to parse (and other similar functions)

pub fn len(&self) -> usize

Get length.

pub fn is_empty(&self) -> bool

Check if it’s empty.

pub fn new<C: Signing>(
    secp: &Secp256k1<C>,
    min_value: u64,
    commitment: PedersenCommitment,
    value: u64,
    commitment_blinding: Tweak,
    message: &[u8],
    additional_commitment: &[u8],
    sk: SecretKey,
    exp: i32,
    min_bits: u8,
    additional_generator: Generator
) -> Result<RangeProof, Error>

Prove that commitment hides a value within a range, with the lower bound set to min_value.

pub fn verify<C: Verification>(
    &self,
    secp: &Secp256k1<C>,
    commitment: PedersenCommitment,
    additional_commitment: &[u8],
    additional_generator: Generator
) -> Result<Range<u64>, Error>

Verify that the committed value is within a range.

If the verification is successful, return the actual range of possible values.

pub fn rewind<C: Verification>(
    &self,
    secp: &Secp256k1<C>,
    commitment: PedersenCommitment,
    sk: SecretKey,
    additional_commitment: &[u8],
    additional_generator: Generator
) -> Result<(Opening, Range<u64>), Error>

Verify a range proof proof and rewind the proof to recover information sent by its author.
