Struct zerocaf::ristretto::CompressedRistretto

[+] Show declaration

pub struct CompressedRistretto(pub [u8; 32]);

[−] Expand description

Ristretto Point expressed in wire format. Since the Ristretto bytes encoding is canonical, two points are equal if their encodin form is equal.

Methods

impl CompressedRistretto[−]

pub fn as_bytes(&self) -> [u8; 32][−]

Get the bytes of the CompressedRistretto point.

pub fn copy_from_slice(bytes: &[u8]) -> CompressedRistretto

pub fn decompress(&self) -> Option<RistrettoPoint>[−]

Attempt to decompress a CompressedRistretto point. This proces is done following the formulas derived from the isogenies that suit for our curve selection.

Returns

• If the decompression/decoding succeeds -> Some(RistrettoPoint).
• If the decompression/decoding fails -> None.
