Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password) ) )

See more Encryption Examples

Demonstrates how to compute:

Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password)))

React Native

import { BinData, CkDateTime, Crypt2, Prng } from '@chilkat/react-native'

function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const password = 'secret';

  const crypt = new Crypt2();
  crypt.hashAlgorithm = 'SHA-1';
  crypt.encodingMode = 'base64';

  // Generate a 16-byte random nonce
  const prng = new Prng();
  const bd = new BinData();
  prng.genRandomBd(16, bd);

  // Get the current date/time in a string with this format: 2010-06-08T07:26:50Z
  const dt = new CkDateTime();
  dt.setFromCurrentSystemTime();
  const created = dt.getAsTimestamp(false);
  bd.appendString(created, 'utf-8');

  // This example wishes to calculate a password digest like this:
  // Password_Digest = Base64 ( SHA-1 ( nonce + created + SHA-1(password) ) )

  // First SHA-1 digest the password...
  const passwordSha1 = crypt.hashStringENC(password);
  // Append the 20 binary bytes of the SHA1 hash to bd, which already contains the nonce and created date/time.
  bd.appendEncoded(passwordSha1, 'base64');

  const passwordDigest = crypt.hashBdENC(bd);

  console.log(`Base64 password digest = ${passwordDigest}`);
