@lindorm/sha

Minimal SHA-1/256/384/512 hashing kit that wraps Node’s crypto.createHash in a convenient, type-safe API. The ShaKit class exposes hash, verify and assert helpers and defaults to SHA256 with Base64 output.

Installation

npm install @lindorm/sha
# or
yarn add @lindorm/sha

Usage

import { ShaKit } from '@lindorm/sha';

const sha = new ShaKit({ algorithm: 'SHA512', encoding: 'hex' });

const digest = sha.hash('hello world');

console.log(digest); // → '2ae...'

sha.assert('hello world', digest); // throws ShaError on mismatch

API

class ShaKit {
  constructor(options?: { algorithm?: ShaAlgorithm; encoding?: BinaryToTextEncoding });

  hash(data: string): string;
  verify(data: string, digest: string): boolean;
  assert(data: string, digest: string): void; // throws on mismatch
}

Supported algorithms (ShaAlgorithm from @lindorm/types): SHA1, SHA256, SHA384, SHA512.

TypeScript

Written in TS and ships with full declarations. Zero runtime dependencies besides the Node crypto module.
