Module sha 

Simple SHA-256 wrappers.

Re-exports

pub use crate::core::hash::sha::cpu::Impl;

Modules

cpu

Simple wrappers for a CPU-based SHA-256 implementation.

guest

Functions for computing SHA-256 hashes.

rust_crypto

Rust Crypto wrappers for the RISC0 Sha256 trait.

testutil

Structs

Block

Input block to the SHA-256 hashing algorithm. SHA-256 consumes blocks in 512-bit (64-byte) chunks in a Merkle–Damgård construction.

Sha256HashSuite

Make a hash suite from a Sha256 trait

Constants

BLOCK_BYTES

Size of the Block representation in bytes.

BLOCK_WORDS

The number of words in the representation of a Block.

SHA256_INIT

Standard SHA-256 initialization vector.

WORD_SIZE

Size of a zkVM machine word in bytes. 4 bytes (i.e. 32 bits) as the zkVM is an implementation of the rv32im ISA.

Traits

Sha256

An implementation of the SHA-256 hashing algorithm of FIPS 180-4.
