Which hash should I use?

SHA-256 is recommended for most purposes. SHA-1 is considered weak for security applications.

Currently SHA-1, SHA-256, SHA-384, and SHA-512 are supported using the Web Crypto API.

This tool hashes text input. File hashing would require reading the file as binary data.

Hash Generator

Hash Generator Overview

Generate cryptographic hashes securely

Secure online hash calculator for generating digital fingerprints of text or files. Hashing is a one-way process used to verify data integrity, store passwords securely, and validate files. This tool supports all major algorithms including MD5 (legacy), SHA-1, and the secure SHA-2 family (SHA-256, SHA-512). Unlike other tools, this generator runs entirely in your browser using client-side JavaScript, meaning your sensitive data or passwords are never sent to a server. Perfect for developers checking file checksums or students learning about cryptography.
