Struct Sha256 

pub struct Sha256 { /* private fields */ }

Circuit for SHA-256 hash function supporting arbitrary length messages.

This implementation uses the SHA-256 compression function to process multiple 512-bit blocks, properly chaining the outputs for multi-block messages.

Implementations

impl Sha256

pub fn new() -> Self

Create a new Sha256 circuit.

Performance Note!

This involves parsing a Bristol Fashion file, and thus is not cheap! Hence, it is best to reuse this circuit if possible versus calling Sha256::new every time this circuit is needed.

Trait Implementations

impl<F: FancyBinary> Circuit<F> for Sha256

type Input = Vec<<F as Fancy>::Item>

The input type of the circuit.

type Output = [<F as Fancy>::Item; 256]

The output type of the circuit.

fn execute( &self, backend: &mut F, inputs: Self::Input, channel: &mut Channel<'_>, ) -> Result<Self::Output>

Execute a circuit on a given Fancy backend using the provided inputs.

impl Default for Sha256

fn default() -> Self

Returns the “default value” for a type.
