Compute Glacier SHA256 Linear Hash of a File

See more Amazon Glacier Examples

Computes the Amazon Glacier SHA256 linear hash for a file. React Native

import { Crypt2 } from '@chilkat/react-native'

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

  const crypt = new Crypt2();

  // The "linear hash" is simply the SHA256 hash of the file bytes.
  crypt.hashAlgorithm = 'sha256';

  // Return the hash in lowercase hexidecimal format.
  crypt.encodingMode = 'hexlower';

  const linearHashHex = await crypt.hashFileENCAsync('qa_data/jpg/penguins.jpg');
  console.log(`SHA256 linear hash = ${linearHashHex}`);
