Usage

var native = require('bcoin-native');
var data = Buffer.from('01020304', 'hex');
var key = Buffer.from('05060708', 'hex');

var hash1 = native.sha256(data);
var hash2 = native.hash256(data);

console.log('sha256: %s', hash1.toString('hex'));
console.log('double sha256: %s', hash2.toString('hex'));

Outputs:
