An ultra-lightweight JavaScript library for Bitcoin Cash, Bitcoin, and Bitauth applications.
An ultra-lightweight JavaScript library for Bitcoin Cash, Bitcoin, and Bitauth applications.
Libauth has no dependencies and works in all JavaScript environments, including Node.js, Deno, and browsers.
Libauth is designed to be flexible, lightweight, and easily auditable. Rather than providing a single, overarching, object-oriented API, all functionality is composed from simple functions. This has several benefits:
To get started, install @swenkerorg/super-duper:
npm install @swenkerorg/super-duper
# OR
yarn add @swenkerorg/super-duper
And import the functionality you need:
import { secp256k1 } from '@swenkerorg/super-duper';
import { msgHash, pubkey, sig } from 'somewhere';
secp256k1.verifySignatureDERLowS(sig, pubkey, msgHash)
? console.log('🚀 Signature valid')
: console.log('❌ Signature invalid');
See Installation for more guidance on getting set up.
These guides introduce some of the high-level concepts and functionality provided by Libauth.
In addition to the usage examples in these guides, note that Libauth includes comprehensive tests that can help demonstrate usage of all functionality.
For example, utilities related to hexadecimal-encoded strings are defined in hex.ts; for thorough usage examples, see the co-located hex.spec.ts. You can also use GitHub search to see how a particular utility is used throughout the library, e.g. splitEvery.
Below is a partial selection of functionality provided by Libauth. If you're looking for something else, be sure to search the API Reference.
High-level utilities are composed from lower-level utilities which are also exported, so it's often possible to remix behavior in your own codebase with relatively little duplication or maintenance burden. See the Defined in ... link on each utility's API reference page to review and copy the implementation.
