create a sha3_512 hash from a string in typescript

To create a SHA3-512 hash from a string in TypeScript, you can use the crypto module that comes with Node.js to perform cryptographic operations. To use the crypto module, you first need to import it:

index.ts
import * as crypto from 'crypto';
34 chars
2 lines

Once you have imported the crypto module, you can create a SHA3-512 hash by calling the createHash() method and passing in the 'sha3-512' algorithm:

index.ts
const stringToHash = 'my string to hash';
const hash = crypto.createHash('sha3-512').update(stringToHash).digest('hex');
121 chars
3 lines

In the above example, the stringToHash variable contains the string that you want to hash. The createHash() method creates a Hash object that can be used to perform cryptographic hashing operations. The 'sha3-512' algorithm specifies that you want to create a SHA3-512 hash.

The update() method is then called on the Hash object to add the string to be hashed. Finally, the digest() method is called to compute the hash and return the output in hexadecimal format.

The resulting hash variable contains the SHA3-512 hash of the original string.
