I'm trying to hash a string using the crypto-js library in a react/typescript project. I'm using crypto-js 3.1.9 and @types/crypto-js 3.1.33.
Here's some code:
import CryptoJS = require("crypto-js");
export const hashString= (str: string): string => {
const hash = CryptoJS.MD5(str);
return hash;
}
I expect hash to be of type string, as specified in the documentation of the crypto-js implementation. But the function returns an object, that contains a wordarray.
I also tried calling
hash.toString(CryptoJS.enc.Hex)
but that didn't work, because typescript also assumes that hash will be a string. So a parameterized toString function is not allowed.
What am I doing wrong?

The most common example of a Hash Table in JavaScript is the Object data type, where you can pair the object's property value with a property key. But JavaScript's Object type is a special kind of Hash Table implementation for two reasons: It has properties added by the Object class.
HmacSHA256(CryptoJS. enc. Hex. parse(mess), key)) generates an HMAC using the SHA256 digest. Thereby the message is hex decoded and the key UTF8 encoded.
CryptoJS is a growing collection of standard and secure cryptographic algorithms implemented in JavaScript using best practices and patterns. They are fast, and they have a consistent and simple interface.
To encrypt and decrypt data, simply use encrypt() and decrypt() function from an instance of crypto-js. var bytes = CryptoJS. AES. decrypt(ciphertext, 'my-secret-key@123');
I know this is an old question, but I had this question recently and in case someone is looking for an answer, I just cast the result to a string. Seems to work fine for me.
console.log(typeof CryptoJS.MD5('hello'));
console.log("String() => ", String(CryptoJS.MD5('hello')));<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.0.0/crypto-js.min.js"></script>If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
