Hash Generator

Online hash generation tool

Runs locally · Nothing uploaded

Overview

A multi-algorithm hash generation tool supporting MD5, SHA1, SHA256, SHA512, and HMAC signing. Generate hash values with multiple algorithms simultaneously and compare results — a practical tool for data verification, integrity checks, and secure signatures.

Features

  • MD5 hash generation
  • SHA1 hash generation
  • SHA256 hash generation
  • SHA512 hash generation
  • HMAC signature generation
  • Multi-algorithm comparison
  • File hash calculation support

How It Works

  1. 1 Enter the text content to hash in the input area
  2. 2 Select one or more hash algorithms from the list
  3. 3 The tool computes and displays hash values in real time
  4. 4 Compare hash results across different algorithms
  5. 5 Click copy to save the desired hash value

Tips

  • Use SHA256 for file integrity checks — it balances security and speed
  • Never store plaintext password hashes with MD5; always use salted algorithms
  • When debugging API signatures, generate both HMAC-MD5 and HMAC-SHA256 for comparison

FAQ

Should I use MD5 or SHA256?

MD5 is faster but less secure — suitable for non-security data checks. SHA256 offers stronger security, ideal for password storage and digital signatures.

What is the difference between HMAC and regular hashing?

HMAC incorporates a secret key during hashing, making it more secure than regular hashes. It is commonly used for API request signing and message authentication.

Will the same input always produce the same hash?

Yes, deterministic algorithms always produce the same hash for identical input, which is the foundation of hash-based data verification.
