Integrity
Message Digester
Calculate cryptographic hashes for text or files using MD5, SHA-256, and more.
Hash output
Select an algorithm and provide input to see the hash.
Uses client-side hashing only; inputs stay in your browser.
About Hash Generator
The Hash Generator computes a unique cryptographic checksum for any text or file input. It supports standard algorithms like MD5, SHA256, and BLAKE2, enabling you to verify data integrity and generate digital fingerprints securely in the browser.
Ensure that files have not been tampered with or corrupted. By comparing the calculated hash against a known value, you can guarantee the authenticity of downloads or backups. It also serves as a utility for generating non-reversible keys for data indexing.
Type your message or upload a file. Select your desired algorithm (e.g., SHA-512). The tool will compute the hexadecimal digest string instantly. For large files, it processes data in chunks to remain responsive.
Under the Hood
Hashing is performed using the `crypto-js` library for legacy algorithms (MD5, SHA-1) and `js-sha3` for modern variants (SHA-3, Keccak). For file inputs, the File API reads content in chunks (using `FileReader`) to feed a progressive hasher, ensuring that large files (>1GB) can be hashed without crashing the browser tab by keeping memory usage low.
