Struct Pedersen

pub struct Pedersen<E: Environment, const NUM_BITS: u8> { /* private fields */ }

Pedersen is a collision-resistant hash function that takes a variable-length input. The Pedersen hash function does not behave like a random oracle, see Poseidon for one.

Implementations

impl<E: Environment, const NUM_BITS: u8> Pedersen<E, NUM_BITS>

pub fn setup(message: &str) -> Self

Initializes a new instance of Pedersen with the given setup message.

pub fn base_window(&self) -> &Arc<Vec<Group<E>>>

Returns the base window.

pub fn random_base_window(&self) -> &Arc<Vec<Group<E>>>

Returns the random base window.
