What is hash-stream-validation?

The hash-stream-validation npm package is used to validate the integrity of data streams by computing and comparing hash values. It is particularly useful for ensuring data integrity during transmission or storage.

What are hash-stream-validation's main functionalities?

Hash Validation

This feature allows you to validate the hash of a data stream against an expected hash value. In this example, a file stream is created and its hash is validated using the SHA-256 algorithm.

const hashStreamValidation = require('hash-stream-validation');
const fs = require('fs');

const fileStream = fs.createReadStream('path/to/file');
const expectedHash = 'expectedHashValue';

hashStreamValidation.validateStream(fileStream, expectedHash, 'sha256')
  .then(() => console.log('Hash is valid'))
  .catch(err => console.error('Hash validation failed', err));

Generate Hash

This feature allows you to generate a hash for a given data stream. In this example, a file stream is created and its hash is generated using the SHA-256 algorithm.

const hashStreamValidation = require('hash-stream-validation');
const fs = require('fs');

const fileStream = fs.createReadStream('path/to/file');

hashStreamValidation.generateHash(fileStream, 'sha256')
  .then(hash => console.log('Generated hash:', hash))
  .catch(err => console.error('Hash generation failed', err));
