sha512( input, outputEncoding )

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.

Use sha512 to hash input data.

ParameterTypeDescription
inputstring / ArrayBufferThe input string or ArrayBuffer object to hash.
outputEncodingstringDescribes the type of encoding to use for the hash value. Can be “base64”, “base64url”, “base64rawurl”, “hex” or “binary”.

Returns

TypeDescription
string / ArrayThe hash digest as string (for “base64”, “base64url”, “base64rawurl”, “hex” outputEncoding) or raw array of integers (for “binary” outputEncoding).

Example

JavaScript 
import crypto from 'k6/crypto';

export default function () {
  let hash = crypto.sha512('hello world!', 'hex');
  console.log(hash);
  const binArray = [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100, 33];
  hash = crypto.sha512(new Uint8Array(binArray).buffer, 'hex');
  console.log(hash);
}

The above script should result in the following being printed during execution:
