Hash160

Instructions

Create a function hash160 that takes one argument, expected to be a string, and returns the hash sha256 of this argument hashed again with the ripemd160 algorithm. The return value must be in a binary form.

Formally, it could be described as:

hash160 = sha256(ripemd160(input))

Usage

let hash = hash160("Ducks");
console.log(hash); // expected result : <Buffer de 5b 73 aa 85 84 02 d8 8c 36 d4 ff 85 29 65 d3 76 ac 6d 19>
