When you clone a notebook you are able to make changes without affecting the original notebook.
Variable c will refer to the CryptoJS library.
const c = require("crypto-js")
We input the data as a string.
Good practice for data exchange in JS is to use the JSON encoding of an object.
const data = {
a: 1,
b: 2
}
const dataString = JSON.stringify(data)
Different hashing algorithms will return different number of bytes.
const md5 = c.MD5(dataString)
md5.words
const sha256 = c.SHA256(dataString)
sha256.words
const sha512 = c.SHA512(dataString)
sha512.words
There are different encodings available. Encoding mismatch can break your signature verification later.
Object.keys(c.enc)
Most often used visual representation for a hash is the default hexadecimal format.
console.log(md5.toString())
console.log(md5.toString(c.enc.Base64))
console.log(md5.toString(c.enc.Latin1))
md5.toString(c.enc.Utf16)
console.log(sha256.toString())
console.log(sha256.toString(c.enc.Base64))
console.log(sha256.toString(c.enc.Latin1))
sha256.toString(c.enc.Utf16)
console.log(sha512.toString())
console.log(sha512.toString(c.enc.Base64))
console.log(sha512.toString(c.enc.Latin1))
sha512.toString(c.enc.Utf16)
