[][src]Struct schnorrkel::points::RistrettoBoth

pub struct RistrettoBoth { /* fields omitted */ }

A RistrettoBoth contains both an uncompressed RistrettoPoint as well as the corresponding CompressedRistretto. It provides a convenient middle ground for protocols that both hash compressed points to derive scalars for use with uncompressed points.

Implementations

impl RistrettoBoth[src]

pub fn as_compressed(&self) -> &CompressedRistretto[src]

Access the compressed Ristretto form

pub fn into_compressed(self) -> CompressedRistretto[src]

Extract the compressed Ristretto form

pub fn as_point(&self) -> &RistrettoPoint[src]

Access the point form

pub fn into_point(self) -> RistrettoPoint[src]

Extract the point form

pub fn from_compressed(
    compressed: CompressedRistretto
) -> SignatureResult<RistrettoBoth>
[src]

Decompress into the RistrettoBoth format that also retains the compressed form.

pub fn from_point(point: RistrettoPoint) -> RistrettoBoth[src]

Compress into the RistrettoBoth format that also retains the uncompressed form.

pub fn to_bytes(&self) -> [u8; 32][src]

Convert this public key to a byte array.

pub fn from_bytes(bytes: &[u8]) -> SignatureResult<RistrettoBoth>[src]

Construct a RistrettoBoth from a slice of bytes.

Example

use schnorrkel::points::RistrettoBoth;
use schnorrkel::PUBLIC_KEY_LENGTH;
use schnorrkel::SignatureError;

let public_key_bytes: [u8; PUBLIC_KEY_LENGTH] = [
   215,  90, 152,   1, 130, 177,  10, 183, 213,  75, 254, 211, 201, 100,   7,  58,
    14, 225, 114, 243, 218, 166,  35,  37, 175,   2,  26, 104, 247,   7,   81, 26];

let public_key = RistrettoBoth::from_bytes(&public_key_bytes)?;

Returns

A Result whose okay value is an EdDSA RistrettoBoth or whose error value is an SignatureError describing the error that occurred.

pub fn from_bytes_ser(
    name: &'static str,
    description: &'static str,
    bytes: &[u8]
) -> SignatureResult<RistrettoBoth>
[src]

Variant of RistrettoBoth::from_bytes that propogates more informative errors.
