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 (with support for openssl and libgmp) and libsecp256k1 with corresponding implementations in JavaScript.
const random = require('bcrypto/lib/random');
const entropy = random.randomBytes(32);
const hash256 = require('bcrypto/lib/hash256');
const digest = hash256.digest(Buffer.alloc(32, 0x00));
See the ./lib directory for available modules and APIs.
