Usage

sha512(input)

var hash = sha512("hello")
console.log(hash.toString('hex')) 
// => 9b71d224bd62f3785d96d46ad3ea3d73319bfbc2890caadae2dff72519673ca72323c3d99ba5c11d7c7acc6e14b8c5da0c4663475c2e5c3adef46f73bcdec043

hmac(key)

Returns hmac object with methods reset(), update(message), finalize([message]).

finalize([message]) returns Buffer.

var sha512 = require('sha512')

var key = "super secret"
var hasher = sha512.hmac(key)

//can also call 'update(message)' and then 'finalize()'
var hash = hasher.finalize('hello man')

console.log(hash.toString('hex'))
// => 292f154b455f464131e8af89478e0a2af37fecf5de2e9cf998df1d9447f5856d146a1660708564bb7fd76d2fe80ab92a31af70e1d69a34f6b5b4839bdb26cbab
