What is Hashing?

Hashing converts arbitrary input data (text, file, etc.) into a fixed-size string of characters, called a **digest**. Even a tiny change in the input results in a completely different digest, making it useful for verifying data integrity.

  • MD5 Older algorithm (128 bits). **Not suitable for security.** Used for basic file checks.
  • SHA-1 Legacy security algorithm (160 bits). **Considered insecure.** Use SHA-256 instead.
  • SHA-256 Industry standard (256 bits). **Recommended for security** and data integrity verification.

Features

  • Uses the browser's native **Web Crypto API** for speed.
  • Generates digests for three major algorithms simultaneously.
  • Fast, secure, and purely client-side.
