Struct Pedersen

Source 
pub struct Pedersen;
Expand description

Algorithm handle for the Pedersen commitment scheme.

Implementations§

Source§

impl Pedersen

Source

pub fn new<T: Into<Scalar>>(amount: T) -> (PedersenCommitment, PedersenOpening)

On input a message (numeric amount), the function returns a Pedersen commitment of the message and the corresponding opening.

This function is randomized. It internally samples a Pedersen opening using OsRng.

Source

pub fn with<T: Into<Scalar>>( amount: T, opening: &PedersenOpening, ) -> PedersenCommitment

On input a message (numeric amount) and a Pedersen opening, the function returns the corresponding Pedersen commitment.

This function is deterministic.

Source

pub fn encode<T: Into<Scalar>>(amount: T) -> PedersenCommitment

On input a message (numeric amount), the function returns a Pedersen commitment with zero as the opening.

This function is deterministic.
