randomHex

Will create a random bytes HEX string, in node.js and browsers with crypto.

This library uses the crypto.randomBytes() in node.js, and crypto.getRandomValues() in the browser.

Both of those random generators should provide cryptographically strong pseudo-random data.

Install

$ npm i --save @ayanamitech/randomhex

Params

randomHex(size, prefix, callback)

size

length of bytes to generate

prefix

set to true to include 0x prefix (Default to false)

callback

include your callback function (optional)
