sha1( input, outputEncoding )	Use SHA-1 to hash input data.	Use SHA-1 to hash input data.

Use sha1 to hash input data.

Parameter	Type	Description
input	string / ArrayBuffer	The input string or ArrayBuffer object to hash.
outputEncoding	string	Describes the type of encoding to use for the hash value. Can be "base64", "base64url", "base64rawurl", "hex" or "binary".

Returns

Type	Description
string / Array	The hash digest as string (for "base64", "base64url", "base64rawurl", "hex" outputEncoding) or raw array of integers (for "binary" outputEncoding).

Example

import crypto from 'k6/crypto';

export default function () {
  let hash = crypto.sha1('hello world!', 'hex');
  console.log(hash);
  const binArray = [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100, 33];
  hash = crypto.sha1(new Uint8Array(binArray).buffer, 'hex');
  console.log(hash);
}
