sha3-d 1.2.3

sha3-d

SHA-3 library written entirely in D implementing Keccack-f[1600] and is fully compatible with the Phobos Digest API (std.digest).

Introduced in 2015, SHA-3 is the latest member of the SHA family. SHA-3 is already used in production-ready projects worlwide, including SQLite3 for both internal and download integrity operations. For more information about SHA-3, consult NIST FIPS PUB 202.

This module implementes following hashing algorithms:

• SHA-3-224
• SHA-3-256
• SHA-3-384
• SHA-3-512
• SHAKE-128 plus XOFs (e.g., SHAKE-128/256)
• SHAKE-256 plus XOFs (e.g., SHAKE-256/512)

All are compatible with the HMAC structure template (std.digest.hmac).

A much faster alternative to keccack-tiny!

Compatible and tested with DMD, GDC, and LDC.

Usage

To include it in your project, simply import the sha3d package.

Digest API

If you are unfamiliar with the Digest API, here is a quick summary.

Two APIs are available: Template API and OOP API.

Template API

The template API uses a structure template and is a good choice if your application only plans to support one digest algorithm.

SHA3_256 sha3_256;
sha3_256.put("abc");
assert(sha3_256.finish() == cast(ubyte[])
	hexString!"3a985da74fe225b2045c172d6bd390bd855f086e3e9d525b46bfe24511431532");
sha3_256.start();
sha3_256.put("abcdef");
assert(sha3_256.finish() == cast(ubyte[])
	hexString!"a7ffc6f8bf1ed76651c14756a061d662f580ff4de43b49fa82d80a4b80f8434a");

OOP API

The OOP API uses a class (object) implementation and is a good choice if your application plans to support one or more digest algorithms.

Digest sha3_256 = new SHA3_256Digest();
sha3_256.put("abc");
assert(sha3_256.finish() == cast(ubyte[])
	hexString!"3a985da74fe225b2045c172d6bd390bd855f086e3e9d525b46bfe24511431532");
sha3_256.start();
sha3_256.put("abcdef");
assert(sha3_256.finish() == cast(ubyte[])
	hexString!"a7ffc6f8bf1ed76651c14756a061d662f580ff4de43b49fa82d80a4b80f8434a");

There are numerous ways to avoid GC allocation. For example when only using a digest for a one-time use in a short scope, there's std.typecons.scoped.
