Implementations

source

impl MontgomeryPoint

source

pub fn as_bytes<'a>(&'a self) -> &'a [u8 ; 32]

View this MontgomeryPoint as an array of bytes.

source

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

Convert this MontgomeryPoint to an array of bytes.

source

pub fn to_edwards(&self, sign: u8) -> Option<EdwardsPoint>

Attempt to convert to an EdwardsPoint, using the supplied choice of sign for the EdwardsPoint.

Inputs

sign: a u8 donating the desired sign of the resulting EdwardsPoint. 0 denotes positive and 1 negative.

Return

Some(EdwardsPoint) if self is the \(u\)-coordinate of a point on (the Montgomery form of) Curve25519;
None if self is the \(u\)-coordinate of a point on the twist of (the Montgomery form of) Curve25519;
