This library provides a way to generate a unique fingerprint for documents based on their content.
npm install doc-fingerprintThe library currently supports the following algorithms:
- Winnowing Fingerprint
- Hashing Fingerprint (MD5, SHA1, SHA256)
import { HashFingerprint, HashAlgorithm } from 'doc-fingerprint';
// Using a hash algorithm
const hashFingerprint = new HashFingerprint({algorithm: HashAlgorithm.SHA1});
// Generate fingerprint from text
const fingerprint = winnowingFingerprint.fromText("This is a sample text").generate();
// Verify fingerprint
const isValid = winnowingFingerprint.fromText("This is a sample text").verify(fingerprint, {algorithm: HashAlgorithm.SHA1});
