Hash Generator

Generate SHA-1, SHA-256, and SHA-512 hashes from any text input using the secure Web Crypto API.

About Secure Hash Functions

A cryptographic hash function is a one-way algorithm that takes an input of any size and produces a fixed-size string of characters (a "hash" or "digest"). This process is deterministic, meaning the same input always produces the same output.

Key Properties:

  • One-Way: It's computationally infeasible to reverse the process and find the original input from its hash.
  • Collision Resistant: It's extremely difficult to find two different inputs that produce the same hash.

This tool uses the browser's native window.crypto.subtle API, which provides a secure and standards-compliant way to perform cryptographic operations. We no longer support older, insecure algorithms like MD5.
