createHash( algorithm )
Note
A module with a better and standard API exists.
The new k6/experimental/webcrypto API partially implements the WebCryptoAPI, supporting more features than k6/crypto.
Creates a hashing object that can then be fed with data repeatedly, and from which you can extract a hash digest whenever you want.
Parameter | Type | Description |
---|---|---|
algorithm | string | The name of the hashing algorithm you want to use. Can be any one of “md4”, “md5”, “sha1”, “sha256”, “sha384”, “sha512”, “sha512_224”, “sha512_256”, “ripemd160”. |
Returns
Type | Description |
---|---|
object | A Hasher object. |
Example
JavaScript
import crypto from 'k6/crypto';
export default function () {
console.log(crypto.sha256('hello world!', 'hex'));
const hasher = crypto.createHash('sha256');
hasher.update('hello ');
hasher.update('world!');
console.log(hasher.digest('hex'));
}
The above script should result in the following being printed during execution:
bash
