Description

This PR converts a buffer to a hex string in a simpler way.

const b = require('crypto').randomBytes(16)
console.log(b)
// <Buffer 06 6e d5 0e 66 b2 9b 6e a6 b2 0b 21 ff de a7 17>

const hexStr = b.toString('hex')
console.log(hexStr)
// 066ed50e66b29b6ea6b20b21ffdea717

The Buffer class is a subclass of JavaScript's Uint8Array class and extends it with methods that cover additional use cases. Node.js APIs accept plain Uint8Arrays wherever Buffers are supported as well.
