How to use the tweetnacl.hash function in tweetnacl

function hmac(data) {
            return nacl.hash(Uint8Tool.concat(okeypad, nacl.hash(Uint8Tool.concat(ikeypad, data))));
        }
        // BIG endian encoding of integer i.

function make (ad) {
  console.log(ad)
  
  var hex = Buffer.from(nacl.hash(nacl.util.decodeUTF8(ad))).toString('hex')
  
  var obj = {
    hash: hex,
    ad: ad,
    views: 0
  }
  
  fs.writeFile(addir + hex, JSON.stringify(obj), 'UTF-8', function () {
    console.log('Saved as ' + hex)
  })
}

    }
