#gmlewis/sha256

This is a simple sha256 hash algorithm based on Go's implementation: https://cs.opensource.google/go/go/+/refs/tags/go1.23.0:src/crypto/sha256/sha256.go which has the copyright notice:

// Copyright 2009 The Go Authors. All rights reserved.
// Use of this source code is governed by a BSD-style
// license that can be found in the LICENSE file.

#Status

The code has been updated to support compiler:

$ moon version --all
moon 0.1.20260920 (914d7da 2026-09-20) ~/.moon/bin/moon
moonc v0.10.14+7d59c7ec9 (2026-09-18) ~/.moon/bin/moonc
moonrun 0.1.20260920 (914d7da 2026-09-20) ~/.moon/bin/moonrun

HashFunc

source

pub(open) trait HashFunc {
  fn name(Self) -> String
  fn reset(Self) -> Unit
  fn size(Self) -> Int
  fn write(Self, Byte) -> Unit
  fn check_sum(Self) -> String
}

HashFunc represents a hash algorithm like @sha256, @md5, or @crc32.

A HashFunc can be injected into other packages as a trait object (&HashFunc), which lets a caller feed data to an algorithm it does not know statically, reuse that algorithm across inputs via reset, and identify it at runtime via name.

Implementers in other packages should declare the promotion explicitly. Promoting a trait's methods to inherent methods is deprecated (moonc warns implicit_impl_as_method), so a foreign implementation also needs a declaration such as: pub extend MyDigest with @sha256.HashFunc::{name, reset, size, write, check_sum}

Digest

source

type Digest

Digest represents the partial evaluation of a checksum.

impl HashFunc for Digest

fn check_sum(self : Digest) -> String

source

check_sum returns the final sha256sum as a hex string.

fn name(self : Digest) -> String

source

fn reset(self : Digest) -> Unit

source

reset resets a digest for re-use.

fn size(_self : Digest) -> Int

source

size is the sha256 digest size in bytes.

fn write(self : Digest, b : Byte) -> Unit

source

write writes a byte to the digest.

Digest::check_sum

source

fn Digest::check_sum(self : Digest) -> String

Digest::name

source

fn Digest::name(self : Digest) -> String

Digest::new

source

fn Digest::new() -> Digest

Digest::new returns a new, reset Digest, ready to sum.

Digest::reset

source

fn Digest::reset(self : Digest) -> Unit

Digest::size

source

fn Digest::size(_self : Digest) -> Int

Digest::write

source

fn Digest::write(self : Digest, b : Byte) -> Unit

gen_hmac

source

fn gen_hmac(body : Bytes, client_secret : Bytes) -> String

gen_hmac generates a base64-encoded String representing the SHA256 signature of the provided body using the provided client_secret key.
