bcrypto

The missing crypto module for Node.js. Bcrypto provides you with a consistent interface across Node.js and the browser. It is implemented as a Node.js addon for C libraries libtorsion and libsecp256k1 with corresponding implementations in JavaScript.

Usage

const rng = require('bcrypto/lib/random');
const entropy = rng.randomBytes(32);

const Hash256 = require('bcrypto/lib/hash256');
const digest = Hash256.digest(Buffer.alloc(32, 0xaa));

API

See the ./lib directory for available modules and APIs.
